   It’s sad to thing that in a few trllions years, living beings will look up and see mostly black, as all the other galaxies have moved beyond their ability to see.

   @Chris Sheep, in about a trillion years, its not going to be all blackness. After most of the local clusters merging into one, its going to be a very beautiful looking Single galaxy.

   But where will we humans be looking from, how would have we evolved over a trillion years, or will we even exist.

   If globally seen, there is an ongoing activity of Galaxy’s that are close to each other and that are being pulled towards each other, while some do escape, than how can they all be globally moving away from each other? How can the balloon be expanding when all the coins are staying relatively in place?

   VDGG,

   One thing is pretty certain. We won’t be looking up from earth in a trillion years. The sun should become a red giant and either completely swallow the earth or cause it to become utterly lifeless a LONG time before a trillion years from now, at least 990 billion or so years according to theories of stellar development.

   How can the balloon be expanding when all the coins are staying relatively in place?

   There are two forces at play; gravity and the expansion. For larger masses and closer objects, gravity wins.

   Your question is like asking ‘if gravity, how can the atoms on the top of my head not fall to the bottom of my feet?” Answer: because there is another force at play, and that force is locally stronger.

    “For larger masses and closer objects, gravity wins.”

    Well that is exactly my point, if gravity between the coins on the balloon wins in 30% of the cases let’s say, than how can the balloon/universe be equally expanding, certainly when you look at that image with all the canals. If so, than isn’t gravity countering the expansion, holding everything together like a chain made out of gravity links, it is doing so at least in our ‘section’, and who says that other sections are so much different than ours, and one ‘section’ or ‘group of clusters’ is entangled with the one next to it … and how do you even define a section when it all flows through each other?

    tl;dr and your post might have covered this, but you are wrong when you say that “these galaxies will achieve some maximum, finite distance between them, and wind up eventually moving back towards one another and merging far into the future.” How did you come to this conclusion?
    Aren’t the galaxies in fact ACCELERATING away from us due to the expansion of space-time?
    Gravity is NOT winning this one.

    @ Chelle “How can the balloon be expanding when all the coins are staying relatively in place?”

    Surely things would stay “relatively in place” if the expansion was the same everywhere. All distances would simply increase in proportion. Local differences in the rate of expansion (however caused) would change the local distribution of mass, and objects attracted by gravity can move towards each other against the the local expansion of the balloon, and one effect will ultimately dominate. Just like walking up a down escalator, where there will be a boundary condition: on one side you will eventually end up at the top, and on the other you will eventually end up at the bottom

15. #15 chelle

    DavidL,

    “Local differences in the rate of expansion … would change the local distribution of mass”

    Yes, but here I come back to my previous question (September 11, 1:38 pm), what defines our ‘section’ or what is ‘local’ as you put it? For instance if you have this row of stars going from one far-end of space to an other:

    … -1-o-o-2-o-o-3-o-o-4-…

    So 1 is far away from 4, and thus they can expand away from each other. But in-between there is 1 holding 2 due to gravity; 2 is holding 3 and so forth, linking everything together. Than how can 1 and 4 move away from each other, when they are indirectly hooked to each other due to gravity, doesn’t it all add up?

16. #16 DavidL

    @Chelle

    Why does a gravitational attraction between 2 and 3 strong enough to cause them to merge imply anything about how strongly the 2/3 combination is attracting 1 or 4? Gravity reinforces existing irregularities. Some masses are so far apart that their separation is increasing faster due to the expansion of the space between them than it is decreasing due to their gravitationally induced acceleration towards each other within that space.

    DavidL,

    “Why does a gravitational attraction between 2 and 3 strong enough to cause them to merge imply anything about how strongly the 2/3 combination is attracting 1 or 4?

    Because gravity works in all and both directions between the elements. And certainly when you start having things that are in a row and the amount of gravity emitted starts adding up, like in that image with all the canals, there you start to get a linkage tube-structure, that could hold things tightly together due to gravity. If gravity wouldn’t be doing it’s thing than there wouldn’t be any of those canals.

    chelle,

    You are assuming that the matter in the universe is lined up in regular rows. That’s not the case. Under the influence of gravity, matter tends to clump together. The real analogy would be something more like
    1oooooo2oo3o4ooooooooooooooooooooo5

    In that analogy, surely you can see that over the long term, 2,3, and 4 would tend to merge, but that clump would tend to separate from both 1 and 5. The actual structure of the real universe is clumpy, so this analogy models the real universe better. Galaxies in the same local supercluster that are moving together now will tend to clump together. Galaxies further separated and currently receding will continue to recede from each other.

    The universe can be equally expanding because the cases in which gravity wins are not some arbitrary 30%, they are exactly those cases in which you would expect the calculated force of gravity to be stronger than the calculated expansion of the universe.

    Is this really that hard to understand? There’s one force pulling things apart. Another pushing them together. For any two objects, you calculate the strength of the two forces acting on them. Theory is confirmed when the results of your calculation match empirical observation. If my head suddenly explodes due to the expansion of the universe, that is a serious problem for physics. But if my head stays together despite the expansion, that is not a serious problem, that is exactly what physics expects. Likewise, physics expects close, heavier coins to stay together on the balloon’s surface while further apart and lighter coins do not.

    How is this difficult to understand?

    I don’t claim that there is no attraction between the merged masses 2 and 3 and outliers 1 and/or 4 , just that there is not enough to bind them.

    In a universe created with stationary matter approximately uniformly distributed in a fixed and pre-existing “space” then what you say is correct, it will collapse

    In a universe created by an explosion propelling material into a fixed “space” then some material will collapse back under gravity, but even here some may initially be given escape velocity and will avoid the collapse.

    But we seem to live In a universe created with stationary matter approximately uniformly distributed in a rapidly expanding “space”. This expansion has a larger effect than gravity for objects separated by vast distances. Some of the matter in such a universe is (and more will become) invisible to us because it is moving away from us faster than the speed of light. This cannot be gravitationally bound to our local galaxies.

    Well this is what I’m questioning, what is the distribution. When you look at that picture with the canals than you can see that there is a structure, where galaxies are closely packed together all through space, so it seems to be structurally tight (close) everywhere, than how can there be a global expansion?

    –

    DavidL,

    “we seem to live In a universe created with stationary matter approximately uniformly distributed”

    No we don’t. There is a canal structure, a framework so to say.

    btw it’s not a problem of collapse or expansion because stuff is being pulled from all directions. There are ‘knots’ everywhere in that canal system, so it can’t be expanding nor can it be imploding, it is keeping itself in balance, like a foam. Yes, there are immense massive ‘knots’ of clusters that are fairly equally distributed, but they are embedded in a gravitational construction that seems to, or has to, counter that expansion rate on a massive scale. See it as wires that connect the coins on the surface of the balloon either the wires also need to be stretchable, if they’re not than they’ll prevent the balloon from expanding, and AFAIK Gravity isn’t stretchable.

    “No we don’t. There is a canal structure, a framework so to say.”

    Yes we do seem to live In a universe created with stationary matter approximately uniformly distributed. The canal structure, if that is what you chose to call it, is the result of gravity operating on the tiny original non uniformities. It will continue to do so until your canals become “lakes”, of which all except the one we are in will ultimately become invisible to us.

26. #26 chelle

    September 12, 2012

    “The canal structure … will continue to do so until your canals become “lakes”,

    I don’t think that these canals can become a ‘lakes’, they are links that connect one knot to all the others with the force of gravity. Just like how our planet or Milky Way stays a tight ‘coin’ on that balloon, in the same way the wires/canals that connect the coins can’t expand, there is one giant gravitational bonding structure.

    Whatever you think, current Theory (in the scientific not everyday sense) predicts they must. If you wish to postulate “canals” that prevent Gravity from being a universal omnidirectional force by constraining it to act only along them in complete violation of all known Physics, then a bit of supporting evidence would strengthen your case.

30. #30 chelle

    September 12, 2012

    David L,

    Of course gravity is omnidirectional, but you can’t deny that just like our solar system is bonded and kept in place by gravity, that those canals are most likely relatively kept in place by gravity, and not just widening/spreading into lakes. Yes some galaxies lose energy and dissolve, but new ones are born as well out of clouds of dust in those canals, adding new fresh gravity to the construction, constantly renewing the strength of those structures.

    “..that those canals are most likely relatively kept in place by gravity, and not just widening/spreading into lakes”

    Your concept of canals seems to be a description of the structure of the universe both as observed and as predicted by the Standard Model. There is no dispute at all that they are the result of gravity, but the issue is what will happen to them in the future. Perhaps my analogy of them turning into lakes was not a good one as you took it to mean expanding your canals. A better one might be that the canals become a string of increasingly isolated shrinking puddles. This is the prediction of the Standard Model. If you think this model wrong that’s fine. Work out how your universe would behave differently from the one described by the Standard model and devise experiments to show which is correct. This is the only way to distinguish a potential Nobel winning maverick original thinker from a serious case of the Dunning-Kruger effect.

    Similarly your idea of “adding new fresh gravity” (i.e. mass) appears to violate the Standard Model in a major way unless you know more about Dark Matter than all the world’s Astrophysicists.

35. #35 DavidL

    September 13, 2012

    Incidentally a serious question for ETHAN if you are monitoring this thread.

    When some M in our sun becomes equal to E/(C*C), our sun becomes a tiny tiny bit lighter, (strictly speaking, a tiny tiny bit less massive) our orbit becomes a tiny tiny bit larger, and some energy radiates out of the solar system. On a cosmic scale, does this energy somehow cause a gravitational effect, or is the entire universe slowly getting less massive too?

36. #36 Wow

    September 13, 2012

    The energy does cause some gravitational effect, but it spreads out the energy and would reduce the curvature of the universe a little. The universe does get less massive. But GR’s maths uses a tensor that includes energy as well as mass.

    If you move some of the mass of the earth out beyond the geostationary orbit of satellites, then the orbit of these satellites gets higher.

    The sun/earth thing is no different. Mass leaves the system within the earth orbit.

    David L,

    “… your idea of “adding new fresh gravity” (i.e. mass) appears to violate the Standard Model in a major way …”

    I was thinking here of star formation in molecular ‘star dust’ clouds in interstellar space, thus within those canals. I might be wrong but I thought that the bundling of matter, into stars and planets, would have a bigger gravitational impact (pull) along with the rise of dynamics generated by those new galaxies, than when they are just a cloud, so one could speak of ‘new fresh gravity’. A cloud of matter can also be pulled and stretched apart from both sides, but a stellar object (star/planet) keeps itself together by rotating and pulls in all directions, there is a new strong link (galaxy) vs. the weak link there previously was (cloud).

38. #38 DavidL

    September 13, 2012

    “I might be wrong but ..”

    You are. You previously thought even defining “local” was a major issue, but now you are postulating gravity changes completely depending on the local distribution of mass. A cloud of matter consists of many small objects, how large and rare do they have to become before they transform into a group of “stellar objects” and suddenly exhibit totally different behaviour?i

    September 13, 2012

    DavidL,

    “You previously thought even defining “local” was a major issue, but now you are postulating gravity changes completely depending on the local distribution of mass.”

    Defining local, and change of impact of gravity, are both related, as it the way that locally they are connected forming one giant structure, that on a larger scale has an impact preventing expansion.

    –

    “A cloud of matter consists of many small objects, how large and rare do they have to become before they transform into a group of “stellar objects” and suddenly exhibit totally different behaviour?”

    When the stars are formed and start to shine light, there is a flip-over point.

    For instance, you can use as a metaphor for SpaceTime a trampoline with a rock in the middle; and an amount of water also on it, that might be in total more massive than the rock, but as a result of weak bonding the water will flow towards the rock. Now freeze all the water into one block of ice and put it on the trampoline, than the rock will roll towards the ‘water’. See how the individual parts of the clouds cannot pull something towards them, while if they are strongly bonded they can. The freezing point is the flip-over point. It is the same with that canal structure it is strongly bonded/connected on a ‘local’ scale, just like that block of ice.

43. #43 Sean T

    September 13, 2012

    Chelle,

    This is pretty basic physics. Consider a spherical cloud of dust and gas, much like that which condenses to form a planet. Let the total mass of this dust cloud be M. Consider a test mass with a mass m. Let r be the distance between the center of mass of the cloud and that of the test mass. In the Newtonian approximation, the gravitational attraction between the test mass and the cloud is GmM/r^2.

    Now consider what happens to the cloud if it collaspes under its own gravitation to form a solid body, ie a planet. Consider the cloud as an isolated system (valid since we’re only considering what happens to the cloud under the influence of internal gravitational forces), and consider a reference frame in which the center of mass of the cloud is stationary. Now, the center of mass of the cloud cannot move unless there is an outside force acting upon the cloud. There may well be such forces in the real universe, but such forces do not come about SOLELY from the internal gravitational collapse of the cloud. Therefore, the collaspe of the cloud into a planet cannot cause a change in the location of the center of mass of the body. The collapse of the cloud into a planet also does not cause a change in the mass of the cloud. Therefore, the gravitational attraction between our external test mass and the newly formed planet would be GmM/r^2, which is the exact attraction that we found previously. Therefore, the gravitational attraction is unchaged whether we have a cloud of small particles or a condensed body doing the attracting.

    Chelle;
    

    Well this is what I’m questioning, what is the distribution. When you look at that picture with the canals than you can see that there is a structure, where galaxies are closely packed together all through space, so it seems to be structurally tight (close) everywhere, than how can there be a global expansion?

    I think what’s causing you problems is that the large scale distribution of matter does not match what your gut tells you it should be, if the universe is expanding. It just does not seem right to you that long strings of higher density will be stable if the universe is expanding.

    There are really two issues here. First, your gut is wrong. Intuition is not a good guide as to what the universe ‘should’ look like if the laws of physics operate the way we observe them to. You need rigorous simulation to really get an accurate picture of what sort of large scale structure we should see, if our theories are correct. Rather than just toying with the ideas in your brain, if you put actual observed values into a high powered simulation, and look at the actual results, then yes, it turns out that the “canal”-like structure we see is a possible and expected outcome for a globally expanding universe with some initial minor heterogeneities.

    So, I think at least part of your issue is just plain incredulity. This does not look like the outcome you think we should get from the math. My advice is: get over it. Thisis the outcome we get from the math. If it doesn’t match your intuition, it is because your intuition is wrong, not because the math is wrong.

    The second issue is assuming instability = instability on some human scale. You are right in that such large-scale structures are ultimately unstable. They will not last forever. The expansion of the universe will tear them apart. But you are talking about a many-billion-year process. We happen to have evolved while in the time period when they still exist. There is not much more ‘why’ to it than that. They are unstable; that does not mean they can’t exist for the entire timespan of human civilization.

    An analogy: if someone said “uranium is unstable. But there is some of it on earth. So physics must be wrong” you’d likely think them a nutter. The fact that uranium is unstable yet exists on earth is very obviously and uncontroversially explained by the fact that we evolved before it all decayed away. No overturning of physics is needed. Likewise, we happen to evolve during the era in which the large-scale structure of the universe is string-like.

45. #45 Wow

    September 13, 2012

    It’s not even multi-trillion year epoch until the galaxies are on their own (let alone the stars pulled apart). Something like a trillion trillion trillion trillion trillion trillion trillion trillion years before the local supercluster is wrested out from their local attraction if acceleration continues to go at its current inflationary rate (I think it’s 8 repetitions of trillion, could be 8 repetitions of billion, though, I don’t have my books here with me).

46. #46 DavidL

    Chelle, I had typed up something similar to Sean T’s post, but seems futile to post it now saying the same again

    I would just add something regarding your SpaceTime metaphor (I think a better word would be “analogy”, but call it what you will). The purpose of such of a metaphor/analogy
    is to explain the observed behaviour of an unfamilar system in terms of the operation of a familiar one. Very useful it is too, but what you must not then do is to extrapolate your metaphor/analogy and expect it to reliably predict unobserved effects in the original system. Electricians by historical accident use the concept of electric current to wire up your house. There is no such thing, but in their professional environment current as an analogy of a reverse flow of electrons works fine. However, nobody would even have thought to try to design a CRT monitor using only this analogy; it would be like expecting to be able to design a machine that could suck shapeless lumps of lead into a tube from a great distance along with some local hot gasses, turning them into a bullet shape and some explosive, before putting them into the top a brass case

47. #47 Wow

    September 13, 2012

    “Electricians by historical accident use the concept of electric current to wire up your house.”

    It was more “electrical fluid”, hence the EE Doc Smith books going on about shorting out of electronics leaving pools of residue all around.

    The model also had current going “the wrong way” from the actual flow (of electrons), hence electrons get the negative charge, because current goes the opposite way to the flow of electrons (the engineers got it wrong).

    But this hop-scotch metaphor and extension to reality is chelle’s troll bread-and-butter david. She won’t give it up even for a big pot of honey.

    In theory maybe yes but not in practice because you are overlooking a number of facts. I made a drawing:
    http://tinyurl.com/cloud-vs-knot

    See how a ‘cloud’ is a ‘weak’ thing, it is being pulled apart and hardly plays any role, but when rotating Stars, Planets and Galaxies are formed than you do have again a ‘strong’ link that holds everything together. This giant gravitational structure is a giant equivalent of what happens on smaller scale.

    –

    eric,

    “It just does not seem right to you that long strings of higher density will be stable if the universe is expanding.”

    It isn’t a matter of what seems to be right or not, it is a matter of can it work or not. And a gravitational construction shouldn’t allow an expansion to happen. It is very simple; the Milky Way isn’t expanding because gravity is keeping it together, the same goes for this giant construction that is holding everything together. Either the ‘expansion’ isn’t countered by gravity, or it is. But than the Milky Way has to be stretched apart, you can’t star cherry picking when or where Gravity works or not.

    the Milky Way isn’t expanding because gravity is keeping it together,

    Correct. The space in which the milky way exists is expanding. The atoms (of the milky way) themselves don’t expand, the space they occupy does. Every time the distance between atoms increases by an infinitesimal amount, the other forces pull those atoms back together, becuse on a local scale, the other forces are stronger. Like magnets on a balloon, the balloon can expand under the magnets while they stay together.

    the same goes for this giant construction that is holding everything together. Either the ‘expansion’ isn’t countered by gravity, or it is.

    Eventually the expansion will win out over these big structures, and we will be left with island galaxies, because over large distances, the expansion is stronger (place the magnets very far apart on the balloon, and their attraction won’t hold them together). But its irrational for anyone to think that because the process hasn’t completed by September 13 2012, it must not be happening at all.

    eric,

    “Like magnets on a balloon, the balloon can expand under the magnets while they stay together.”

    The balloon can’t expand because the magnets or coins are linked by gravity-wire’s that are the canals/links of that giant structure, that is what you are overlooking along with the difference of impact of a lose Cloud of matter vs. a Structure of matter.

    Expansion of space is most likely wrong, we observe an expansion because the day our galaxy started to form we started to effect the incoming light from other stars, it is us who are causing the effect of expansion, we are expanding into space, it isn’t a major outside thing that is going on.

    I have to agree with Wow, your comment here makes very little sense to me. I do not understand what you are trying to say. If it’s that space which is deformed by gravity can’t expand, I’d ask why and where you got that rule from. I see no prima facie reason why it can’t. Go back to the old high school metaphor of a bowling ball on a rubber sheet, and it is pretty easy to visualize how the rubber sheet could simultaneously be deformed by the ball and stretched at the same time.

    It’s like saying that actual, real-world wires can’t expand if there’s a force greater than the elasticity of the wire pulling it apart.

    Yes, one can stretch things such as a balloon, but if you look at our Solar System or the Milky Way (the coins on the balloon) they aren’t stretched by the Expansion of Space, so Gravity isn’t stretchable it simply keeps things in its place. The point that I’m making here is the fact that the giant Canal structure is made out of Gravity links, so when things on a small scale can’t be stretched, than how could it be possible on a large scale?

    “In physics, the center of mass or barycenter is the weighted average location of all the mass in a body or group of bodies. Various important calculations in mechanics become simplified when quantities are referenced to the center of mass, or when the entire mass of a body is treated as if it is concentrated at the center of mass.”

    David L,

    In the case of a rigid body, the center or centre of mass is fixed in relation to the body, …

    In physics, a rigid body is an idealization of a solid body of finite size in which deformation is neglected. In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.http://en.wikipedia.org/wiki/Rigid_body

    Now for a cloud everything can shift, and things can be pulled apart. What is so hard to understand about the difference between a solar object, and a cloud of dust … pfff …

63. #63 David L

    September 13, 2012

    Notice the definition is an idealisation. There is no such thing as arigid body in the real universe. All objects deform in response to applied external forces. Even Jupiter’s piddling gravitational field can turn its moons to mush. You are trying to draw an imaginary line again.

64. #64 CB

    September 13, 2012

    The solar system is not a rigid body. The galaxy is not a rigid body. In any body, a force stronger than that holding it together will pull it apart. Gravity does not hold things in place, it attracts them, and anything pushing away harder than gravity pulls will overcome it. This is how rockets work…

    And then you have a phenomenon which is very small but constant across space, so very close things are not pushed apart much and gravity dominates, but over very large distances this effect dominates.

    What’s so hard to understand about that?

    There are no ‘very large distances’. Those canals are dense structures, just like a cable is a dense structure, expansion can not pull these canals apart, they are loaded with gravitational knots keeping everything tight. You keep on forgetting that gravity adds lineary up in these canals.

    Chelle, you moron, the universe is expanding. That is the source of energy that makes the galaxies further apart. But if the overall energy is still not enough to make a stable orbit, the orbit will decay and the two entities will get closer overall.

    They will, however, get closer LESS QUICKLY than if there were no expansion.

    There is no balloon.

    As always, you reify the analogy and pretend it is actually real (like your earlier statement about how your METOPHORICAL water somehow must be real becauase water exists in reality).

80. #80 Chelle

    The stretched balloon is getting warm because each point is losing (bonding) energy. Now our Earth doesnt lose energy when a rocket moves away, but if we want to move away from all the other planets in the universe, than we have to put in work, certainly when there’s an acceleration just like ‘Reza Bokat’ says. So this force has to come from within us, and thus we should lose energy to counter Universal gravity that we can witness in that giant canal construction, but it turns out that there is no such thing because our Milky Way is not expanding, in fact gravity works just fine.

    An apology about the analogy v. metaphor thing. I did a web search as a refresh on the difference, and came up with this:

    “Analogy basically gives similar relationship to two things while metaphor replaces the meaning of one word with another.”

    You are right, it are the points that apply the force and stretch the material that are losing energy, so when planets are moving away from each other, it are those points that do the work and need to lose ‘bonding’ energy, just like CB’s rocket needs to lose energy, and do work to ‘break away’ from Earth.

    Now when we look at ourselves, as a point, we aren’t losing energy but according to Expansion of Space, we should be losing lot’s of energy because we are accelerating away from all the Stars in Deep Space, shrinking within that giant structure.

    –

    Space is expanding.

    Your Stars can’t be moving along with that Expanding Space, because gravity is keeping those clusters in place, that is the problem. Look at the image linked to below, and see how there is a ‘valley’ in SpaceTime where a canal is and where gravity links those clusters:

    http://tinyurl.com/canal-valley

    If you want to expand that structure by expanding space, than Space needs to be a substance that is like a gas that is expanding, and that applies pressure on the elements, and which is doing the work. If so than you can start to push all the clusters away from each other, otherwise the force has to come from within the clusters itself and that is not possible because it would be like ‘Reza Bokat’ suggested, ‘contradict Newton’s second law’. And the interesting thing is that SpaceTime is all about gravity, so no Space cannot just expand without something applying a Force in-between the points. Just like an expanding balloon is the result of more gas being added on the inside pushing all the coins further away from each other, no expanding gas no expansion, and looking at the canal-structure it is even not possible that everything is equally expanding away from us. The only solution for Red Shift *effect* is that space around us is gradually getting denser, dimming down the incoming light.

    I am struggling to understand your previous post, but maybe this is because you are too. Are we also agreed that the expansion of the universe is moving the grid lines of your canal-valley diagram further apart in both axis (increasing the gravitational potential energy between the red balls in the process), and that gravity will be trying to pull the red balls together again, causing them (and their distortions) to move towards their mutual centre of mass with respect to the grid lines?

    Oh great, so now when I trow a ball, it is no longer moving, but it is the space between the ball and my hand that is expanding, super! And stars that are seemingly moving away, happens because space had a push one day and it keeps on going, expanding, dragging everything along with it. The connection between space and matter is even stronger than gravity, btw I thought that it was Space that was curved by Gravity and besides that simply flat, but now Space has mass as it can pull other mass along with it, well what is the mass of a cube of Space, that is flying into space?

    This doesn’t make any sense. First of all there ‘is’ no expansion; and second gravity is not pulling them ‘again’ together, because there ‘was’ no expansion; and third, what’s up with you and this ‘mutual centre of mass’ can’t you see how the canal system distributes the effect of gravity into a structure, like I said a couple of times now gravity adds up when you put things in a row behind each other, it are those canals!

    Yes ‘c’ changes as it is dependent on the excitement of the Aether, we have discussed this before. And no it is not a measurable value, how can you measure the difference between the density here and that of a lightyear away from here, it’s like measuring the water temperature in the Mediterranean and wanting to prove that there is colder water on the north-pole.

    Chelle, I think you have grossly overestimated the density and uniformity of the ‘tubes’ of structure in the universe.

    However as your own link to the zoomed-in images of the cosmic structure shows, certain galaxy clusters may be dense but the filaments between them are not. So in reality, there really are “very large distances” between gravitationally bound structures. You have turned a qualitative eye-balling of an image into a falacious quantitative statement.

    For example, as explained in Ethan’s post, outside the local group, the next closest structures are so far away that their gravity cannot hope to overcome universal expansion in the long term. For this not to be the case we would need many more galaxies evenly spaced between us and the components of the larger supercluster. And this is not the case.

     Chelle

     Please define “rigid body” and please describe how one behaves differently from a non-rigid body. Neither GR nor the Newtonian approximation make such a distinction.

     Now, if you want to argue that external gravitational forces could influence the cloud of gas and dust to a greater degree than they would a planet, maybe I can understand your argument. However, it’s still wrong. An extended body (whether rigid or not, whatever that might mean), can, for the purposes of predicting gravitational interactions, be replaced by a point mass located at the body’s center of mass. That’s true whether the body is a planet or a dust cloud. External bodies will influence both in exactly the same way, namely an external body will cause the center of mass of the body to accelerate.

     The only difference between the two cases is intuitive, not rooted in physics. Take, for example the gravitational interaction between a falling object and the earth. We normally state (at least in classical physics terms) that the falling body has been accelerated. We would be equally correct in stating that the earth has been accelerated. The force acting on the falling body and the force acting on the earth are the same. The earth accelerates less, though, because its mass is much greater.

     In similar fashion, the center of mass of a planet or a dust cloud will be accelerated equivalently by an external body (asssuming, as I have been that the mass of the dust cloud and that of the planet are equal). The result will be more noticeable for the dust cloud. The various particles can shift around more or less independently, so we would notice as change in the size and/or shape of the cloud, whereas with the planet, we might not notice anything. The point remains, however, that the acceleration of the COM is identical in both cases.

     Chelle,

     “A cloud of dust can be pulled apart…”

     By which, I suppose, you are implying that a planet (or other planet-like “rigid” body) cannot be pulled apart? Have you ever looked through a telescope at the planet Saturn? Did you notice those rings that surround the planet? Where do you suppose those rings came from?

     Light would be scattered when it would be slowed down by an other object in the Aether, not when the Aether itself is has a small density difference. An arrow shot on a cold day will still move straight forward as being shot on a warmer day, only when it is raining it will start to ‘scatter’, see the difference.

     Sean T,

     Ridgid or not is a matter of being ‘connected’ or in orbit (rotational momentum) vs. ‘stationary’ and independent molecules, or how easily you can pull things apart. For instance it is harder to stop a planet rotating around a Star, than pull the same amount of dust into one direction, an other example is when you pull on a feather or any other rigid body, you pull the whole feather along because it is chemically bonded in a stronger way than a ‘cloud’ of particles. Or do you find that the particles of a cloud are as strongly connected as in a gas-giant?

     Not necessarily, and that’s my point. For instance, you could attach your feather (or other rigid body) to very strong cables at two distinct points. You could then attach each of these cables to the tail of a 747 aircraft. Now if these 747′s proceed to pull the feather in opposite directions, is the whole feather really going to go along or is it going to tear in half, thus becoming a non-rigid body?

     That’s really my point; given a strong enough force pulling a body apart, there’s no such thing as a rigid body. This doesn’t change the physics of gravitation, however, as I outlined above. The center of mass of the cloud and the center of mass of a planet move the same way under the gravitational force of an external body.

     It is no harder or easier to pull a cloud of dust in one direction than it is to pull a planet of the same mass in one direction. It is true that there’s less of a connection between the individual dust particles than there is between the individual particles making up a planet. Therefore, when you bring an external mass near a cloud of dust, SOME of the dust particles will indeed move toward the external mass. However, not ALL of the particles will do so, only those nearer to the external body. For the planet, ALL of the particles will move toward the external body, just that they will move a much smaller distance than the dust cloud particles. The COM’s move in the same way, however.

     You seem to like analogies that have questionable applicablility to the question at hand, so let me present one of my own to you. Suppose you are protecting a loved one from an animal onslaught. You have a choice of protecting your loved one from a charging elephant or a swarm of bees with the same total mass as the elephant. (Assume that your loved on is allergic to bee stings and will die if he/she is stung, and further assume that the elephant will trample him/her to death). Which one is easier to protect your loved one against? Personally, I’d choose the elephant because given a big enough gun, I’d have a pretty good chance of conclusively stopping the elephant. With the elephant-sized bee swarm, it would be too hard to make sure none got through. Of course, as I’ve said, this has questionable applicability, but hopefully it gets the nature of the problem through to you.

     Sean T,

     You are correct when it’s about you & your partner as a duo vs. a swarm or an elephant, it is a two ‘body’ situation. But you when looking into space and that giant canal structure you are talking about interplay between multiple elements. So in a two body-setting you can pull a 747 forward without breaking, but when there are multiple objects involved it becomes difficult.

     So when you have for instance a harem of 13 girls, than those bees will split up in 13 groups, the elephant can only go in one direction. In that case I would also pick the elephant and have him trample that only one chick, leaving me with 12 others. Now imagine us hanging all in space with the white elephant in the middle, than we all would all move towards the elephant vs. the bees would we would pull towards us, because our rigid body is more strongly connected … although this again depends on how we are connected to other elements … see how it becomes an interplay of a group vs. an individual, AND distance.

     btw In my comment on September 13, 1:00 pm, I also quoted a piece from wikipedia on what a rigid body is and it says clearly that it is an ‘idealization’, so yes it is all relative, but not irrelevant.

     “In physics, a rigid body is an idealization of a solid body of finite size in which deformation is neglected. In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.” http://en.wikipedia.org/wiki/Rigid_body

     Anyway let’s look back at why I brought this concept up in my comment on September 12, 1:01 pm:

     “Yes some galaxies lose energy and dissolve, but new ones are born as well out of clouds of dust in those canals, adding new fresh gravity to the construction, constantly renewing the strength of those structures.”

     It was to point out that the parts that make up that giant structure renew themselves all the time, so when you look at the proposed Expansion of Space that is supposedly pulling everything apart, than you also need to look that refreshing structure based on mass and gravity, being a pretty solid thing, that is actually holding everything in place over time and distance.

     Hobby Everly,

     I overlooked your post. You are definitely right that space in between is very large and seems to be too large. That is the essential question. But the picture of those canals shows us that structures are in fact there, and they are based on gravity, if you would be right than no structures would develop. What you are missing is that gravity adds up, forming valleys and canals as earlier suggested, and than what looks like some lose clusters becomes part of a rigid construction, a bit like a spider web or the Eiffel Tower.

     Well Chelle, after picking up this thread after a weekend away, I am beginning to think that under that polite exterior you are as mad as the proverbial Hatter, though I do wonder if you inspired Ethan’s “Its never too late — to do science” post.

     “Ahem, there is no Aether ‘observable’”

     Indeed! Like Ley Lines, Fairies, Leprechauns,Yeti the Flying Spagetti Monster and any other of the tens of thousand of deities from cultures past and present. Whatever these deities may have done in the past, they all seem incapable doing anything now that has any observable effect whatsoever on the universe. Your Aether goes one step further. Not only is it never observed, it seems to deliberately get out of the way whenever we try to measure it. As GPS satellites whizz around the earth it seems to disperse around them so as to delay or speed up their signals by not even a femtosecond more than general relativity predicts..

     Consider a thought experiment. Imagine your feather and an identical one placed stationary with respect to our sun and away from the gravitational influence of the other planets.Let both drop towards the sun, but before doing so, cut one of them into pieces, How many pieces must you cut this feather into before those pieces fall at a different rate to the intact feather? Is this dependent on how far apart you move the pieces?

     To summarise your ideas as I understand them.

     Gravity is not just proportional to mass, but is also a function of both what for the sake of argument I shall call the nebulosity and the rigidity of the mass involved. The meaning of these terms can be redefined at any time when necessary to fit your arguments.

     A lot of scientists have worked for a long time to produce a Theory of development of the Universe. A computer program based on this Theory simulates the universe from t =(approx)0 to t =13.5 billion years and comes up with something that looks like the universe we observe. You are happy to accept this prediction and the resulting universe of your knots and canals, but otherwise they have got it all wrong. You clearly believe the structure of the universe is dynamic, so what do you think it looked like a billion years ago? (As you have already accepted the width of your canals is only a “not very large” distance of a few million light years and their length a few hundred million light years, your network is only visible to us in a universe at least a billion years old. )

118. #118 chelle

     September 17, 2012

     DavidL,

     First of all I’m not alone about this Aether thing, Einstein also said there is one, only not observable (see the debate at post “Can You Get Something For Nothing?” Feb. 2, 2011). Second your argument about GPS satellites is interesting because if there would be no medium than light would have no maximum speed, what would be limiting it, and what would be causing time dilation?

     So why aren’t we able to observe the Aether, it is in line with my comment on the Happy Gilmore post, that rotation and profile reduces the effect of a ‘medium’ slowing down the Golfball. You need to look at a photon as a kind of closed looped eddie in a Medium, it is governed by it’s own being and isn’t affected by any ‘wind’, the Medium has little grip</i< on the 'object'. It cuts like a knife through butter, so to say.

     Regarding the feather; cut in pieces, or as a whole, it will fall at the same speed towards the Sun, it's a matter of scale. But look at a rotating gyroscope it doesn't fall at all to the ground, and seems to be weightless: http://youtu.be/cquvA_IpEsA

     Imagine it being a non-rigid structure of dust, …

     “A computer program based on this Theory simulates the universe from t =(approx)0 to t =13.5 billion years and comes up with something that looks like the universe we observe.

     Well at Pixar Animation Studios they can roll out a movie such as Brave out of their computers, it also looks very much like real people we observe, I’m not impressed. A good bookkeeper can make anything match therefor it is not scientifically solid.

     You clearly believe the structure of the universe is dynamic, so what do you think it looked like a billion years ago?”

     I believe that a billion years ago, it looked very much like it looked now perhaps slightly different, I’m only saying that we can’t tell from our perspective, and that what we say are the *symptoms* of the Big Bang, e.g. Red Shift is only an *effect* due to the birth of our Milky Way in the Universe, which is ever expending and emitting light and gravity further into the giant bath of Aether, that the Universe is. So what we see is our own little Bang, not that of the Universe.

     btw I think you might be right that Ethan’s “Its never too late — to do science” post might be inspired by our debates, seems like all can learn a *new* thing or two, if you manage to over come and adjust your existing Muscle memory that says that there is NO Aether.

     Chelle,

     As I’ve asked you before, what difference does it make whether or not Einstein thought the aether exists? Either it does or does not, regardless of Einstein’s opinion of the matter. You are clinging to an argument from authority.

     Further, what evidence is there that an aether does exist? If it does, it must have no observable properties and no observable effect on the rest of the universe. Cling to the aether if you must, but there’s really no reason to believe it exists; physics works without it. The fact that you can’t seem to believe that this is the case seems to be nothing more than an argument from incredulty on your part and is just as much a fallacy as your argument from authority.

125. #125 Wow

     September 17, 2012

     Einstein’s thought on the matter was after 18 years of looking, it couldn’t be found, therefore doesn’t exist.

     Sean T,

     “… physics works without it.”

     The Wave- Particle duality that comes out of the Double-Slit experiment shows that there is a medium, if there is no medium than this *effect* is impossible. Mathematically we have come up with a statistical solution for this phenomenon, but that doesn’t take away that there is a medium. So simply put the math works without it, but not nature. That is also what Einstein said, it needs to be there for nature to ‘work’ but there’s no way we can measure it because our measuring tools are build around the exchange of photons … so we have to give up on trying to find it. But now we can do CFD simulations, this opens a new door for trying to figure out how this Aether might work. Not trying this because there is supposedly NO Aether is keeping science once again in the dark ages.

127. #127 Wow

     September 17, 2012

     “The Wave- Particle duality that comes out of the Double-Slit experiment shows that there is a medium”

     No it doesn’t.

128. #128 Sean T

     September 17, 2012

     No Chelle, the effect is quite possible without a medium. It’s your understanding of it that is lacking. Positing a medium just speaks to your own incredulity, ie “there must be a medium because I can’t understand how you can account for this effect without one.”

     In reality, the wave-particle duality that you think presents a problem for the lack of aether is a problem only in your mind. No medium is necessary to explain wave-particle duality, or any other quantum effect. Wave particle duality mostly is a result of our human tendency to classify seemingly different things into different classes. We made a mistake with waves and particles, however. Waves and particles are not inherently different, as becomes apparent on small scales. There is no “duality”; quantum entities are BOTH waves and particles. It’s just that our measuring devices distinguish one or the other aspect of these entities. No need for a medium; all quantum entities have an amplitude and a phase, and can therefore interfere with themselves destructively and constructively to form the interference patterns that arise in the double slit experiment.

     BTW, if you insist on continuing to use Einstein as the source for your arguments from authority, I feel obligated to inform you that in the realm of quantum mechanical phenomena, Einstein is far from an authority. In fact, Einstein, both by his contemporaries and by current physicists was generally considered to have been completely wrong in his ideas. For instance, he believed that the randomness at the heart of the “statistical solutions” that you seem to denigrate was not real and was a manifestation of our lack of knowledge of “hidden variables”. Well, I forget the exact experiment (someone else feel free to help please) but it was found that Bell’s inequality holds, which implies that either there are no hidden variables or that reality is non-local (which would have APPALLED Einstein). So Einstein’s saying that the math works but nature doesn’t is not particularly compelling.

129. #129 DavidL

     September 17, 2012

     “if there is no medium than this *effect* is impossible.”

     If for the sake of argument we assume this to be true, then you need to define the properties required of that medium. You can call it Aether if you like, and insist that lo EM radiation travels through it at a constant speed c. The one defining property that we know it must then have from every experiment that has ever been done is that each and every observer must somehow drag with him both his local Aether, and the Aether through which any of his experimental photons have traveled.

     And how has your billion year old universe been expanding into the Aether without any changes in form? What is causing it to expand when gravity should be continuously pulling it together?

130. #130 chelle

     Sean T,

     ” In fact, Einstein, both by his contemporaries and by current physicists was generally considered to have been completely wrong in his ideas.

     I used Einstein in this debate here, in the first place not say that what he says is right or wrong, but because DavidL started to bring up a bunch of nonsense because I spoke about the fact that the Aether is not observable. This is a normal physics argument and not the stuff what fairytales are made of, which he wanted to suggest it is. And no, it is not all like the Copenhagen interpretation want us to believe it is, check this Double-Slit experiment: http://www.nature.com/news/2011/110602/full/news.2011.344.html

     “Intriguingly, the trajectories closely match those predicted by an unconventional interpretation of quantum mechanics known as pilot-wave theory, in which each particle has a well-defined trajectory that takes it through one slit while the associated wave passes through both slits. The traditional interpretation of quantum mechanics, known as the Copenhagen interpretation, dismisses the notion of trajectories, and maintains that it is meaningless to ask what value a variable, such as momentum, has if that’s not what is being measured.”

     And check the Pilot-Wave theory Wikipage:

     The Pilot Wave theory is a hidden variable theory. Consequently:

     • the theory has realism (meaning that its concepts exist independently of the observer);
     • the theory has determinism.

     The positions and momentums of the particles are considered to be the hidden variables. The observer doesn’t know the precise value of these variables which introduces uncertainty into the theory.

     A collection of particles has an associated matter wave, which evolves according to the Schrödinger Equation. Each particle follows a deterministic (but probably chaotic) trajectory, which is guided by the wave function; collectively, the density of the particles conform to the magnitude of the wave function. The wave function is not influenced by the particle and can exist also as an empty wave function.

     The theory has nonlocality, which makes it compatible with Bell’s theorem.

     Sure we can now still argue about ‘nonlocality’.

     I don’t get very well what you are saying here, but if you have bubbles of air rising in water and consider them as a particle, than they aren’t dragging along the water around them but surely you could measure the vibrations they make when traveling through the water.

     “And how has your billion year old universe been expanding into the Aether without any changes in form? What is causing it to expand when gravity should be continuously pulling it together?”

     I’m not saying that the Aether is Expanding, all I said is that we are expanding in the Aether with our ‘Little Bang’ the day the Milky Way was born out of a cloud of cosmic dust, and Stars start to shine.

     when you pull on a feather or any other rigid body, you pull the whole feather along because it is chemically bonded in a stronger way than a ‘cloud’ of particles.

     If you understand how the EM force can overwhelm an opposing gravitational force, then why don’t you understand how a gravitational force can overwhelm the expansion? The analogy to a rigid body might not be great but you seem to grasp the general solution here; just apply the lesson you’ve learned from ‘what happens when the EM force is locally stronger than gravity’ to ‘what happens when gravity is locally stronger than the expansion.’ The feather stays together. At least temporarily.

140. #140 chelle

     eric,

     I have no problem with the fact that gravity would be locally stronger than the Expansion, keeping things together. This was also part of my motivation that Expansion isn’t working, because on a ‘global’ scale gravity is holding that Giant Structure together, while on a ‘small’ scale gravity keeps the Milky Way together, both are ‘rigid’ structures, countering Expansion. The argument about the feather started about the fact that within the ‘canals’ cosmic dust clouds with a ‘weak’ gravitational bonding structure, reform themselves into tight (rigid) points: Stars and galaxies; so that giant structure keeps on ‘refreshing’ its composure and keeps on being tightly bonded, and thus countering the Expansion.

145. #145 DavidL

     September 18, 2012

     As Wow says, this is probably futile but here goes anyway. I see no need to “adjust [my] existing Muscle memory that says that there is NO Aether.” because the difference between “there is no Aether” and “there is an Aether but it has no observable effect on our universe” is one of semantics not science. One is shorthand for the other.

     However, your existing “Muscle memory” seems to be locked onto the idea that there must be an Aether just as some people know that there must not only be a God, but He must be their exact God. All evidence to the contrary must be somehow explained away however ludicrous those explanations have to become. You seem to genuinely believe that if even a few of the world’s astrophysicists had half your insight we would have found the Aether by now. If you cannot specify the expected properties of your Aether you can never find it. Pauli was reputedly embarrassed at postulating the neutrino because he thought it could never be seen, but unlike your Aether it was at least needed to make equations balance. and its properties well enough define to allow its presence to be detected as technology advanced .

     I will repeat again Every measurement that has ever been done shows the speed of light if the same in every direction regardless of the direction of travel through any Aether. Not only has this been verified to very high precision, it is the central tenet of Einstein’s Theory of Relativity. There must be hundreds of millions of GPS receivers built to thousands of designs sold around the world. Not one, even those used for military applications and precision low-bandwidth seismic monitoring, has ever claimed to give more accuracy by determining which way the receiver and/or the satellites are moving through the Aether.

     If you think the universe of 1 billion years ago looked much as now, how far do we have to go back before it was different? How did it look when it started and how long ago was it?

     Incidentally despite your incredulity at the idea of there being no Aether, I personally find the idea that “space” as we perceive it in our universe is some sort of emergent property of the “stuff” in it causes less incredulity on my part than your concept of an infinite array of pre-existing empty “space” into which your (over 1 billion year old) fixed universe is radiating energy and gravity. Like your comments here, this particular statement is one of personal gut feeling based on no science whatsoever.

146. #146 eric

     Chelle:
     

     I have no problem with the fact that gravity would be locally stronger than the Expansion, keeping things together. This was also part of my motivation that Expansion isn’t working,

     But you agree that gravity works on the feather, right? It doesn’t ‘stop working’ just because the EM force is holding the feather together. One force does not stop the other force from working, it just counteracts the effect you might otherwise see. The bottom of the feather does not fall if you are holding the top, but we still say that gravity is working on the feather.

     Apply that lesson here. The space in which two gravitationally bound objects expands. The fact that they do not move apart does not imply that the expansion “isnt’ working.” It just means the force of gravity holding them together is stronger than the expansive force pushing them apart – but the expansive force is still there, stil working, the same way gravity is still there working on the bottom of the feather, even if it doesn’t fall.

     eric,

     I agree with what you are saying, but the problem is that Expansion is going equally accordingly to the Redshift measurements, and Hubble constant, in all directions (x,y,z). But if you have a construction made out of Gravity, that works against the Expansion and which is a rigid framework, than the Stars can no longer be equally moving away from each other in all directions (x,y,z). Look at this image and compare A with B:
     http://tinyurl.com/Canal-Structure-Expansion

     For A there is no gravity connection between those 2 points, while for B there is a strong connection. So it can’t be that they all are moving away at the same speed from each other, and certainly not away from us, all in the same direction, away from us. So either Gravity has no influence and than the Milky Way is expanding into pieces, or it has influence, and than the Expansion can not cause Stars to move Equally away from each other, and AFAIK the Milky Way is bounded together.

     DavidL,

     the difference between “there is no Aether” and “there is an Aether but it has no observable effect on our universe” is one of semantics not science.

     You are twisting a few words around here, it has observable effects, such as Wave-Particle duality, to have a wave you need to be a medium, but the issue is how to measure it. You can measure Gravity, but you could also see it as an effect of the Aether, that’s how Einstein saw General Relativity as a new introduction of the Aether after he left it out in Special Relativity.

     –

     You seem to genuinely believe that if even a few of the world’s astrophysicists had half your insight we would have found the Aether by now. If you cannot specify the expected properties of your Aether you can never find it.

     We haven’t had the CFD tools up until now, and you also have the issue of people like you, Wow and others that have been thought at school that Aether does NOT Exist, which is a misconception as I’ve tried to show you over and over again. Lorenz and Einstein where no dumbasses, and if you know your history, than the fight was mainly against Heinrich Hertz his kind of Aether.

     btw you also need to look at the political issue, and here I bring up your friend Pauli, he was part of the Copenhagen group that heavily campaigned in favor of it its own ‘interpretation’, as many things in history the story of those who lose isn’t mentioned in schoolbooks such as that of Louis de Broglie. It is known that Pauli was a bit of a bully just like ‘Wow’ that hangs around on this forum, Wolfgang Pauli even put Ralph Kronig down when he proposed ‘Spin’, anyway read this:

     From this idea, de Broglie developed the Pilot Wave theory, and worked out a function for the guiding wave. Initially, de Broglie proposed a double solution approach, in which the quantum object consists of a physical wave (u-wave) in real space which has a spherical singular region that gives rise to particle-like behavior; in this initial form of his theory he did not have to postulate the existence of a quantum particle. He later formulated it as a theory in which a particle is accompanied by a pilot wave. He presented the Pilot Wave theory at the 1927 Solvay Conference. However, Wolfgang Pauli raised an objection to it at the conference, saying that it did not deal properly with the case of inelastic scattering. De Broglie was not able to find a response to this objection, and he and Born abandoned the pilot-wave approach. Unlike David Bohm, de Broglie did not complete his theory to encompass the many-particle case.

     Later, in 1932, John von Neumann published a paper claiming to prove that all hidden variable theories were impossible.
     http://en.wikipedia.org/wiki/Pilot_wave

     –

     If you think the universe of 1 billion years ago looked much as now, how far do we have to go back before it was different? How did it look when it started and how long ago was it?

     How would I know, this is way beyond our grasp. I only know for sure that we as Solar System in a Galaxy where one day born and that we are expanding at the speed of light further into to space, and that this is expanding influence is the most logic cause for Redshift. If you blow with a propellor harder and harder in the direction of a sound source than it will also look as if that speaker is moving further and further away, certainly when it is omni-directional and everything is moving away at the same speed.

     –

     Like your comments here, this particular statement is one of personal gut feeling based on no science whatsoever.

     No it is not particularly about a ‘gut feeling’ rather a rational look at how things can work how they can’t work if there is no Aether in reality.

     Chelle, every atom of your body is attracted to every atom of mine.

     I’m not hitting on you, it is just an inescapable consequence of the Law of Gravity. It applies if we are standing next to each other, on opposite sides of the world, or at opposite ends of your Arrow B or your Arrow A. Why do you think there are regions in space where this law is violated?

     “How would I know, this is way beyond our grasp.” Beyond yours, but the standard model comes up with a pretty good estimate. And of course you have no problem stating what the universe looked like a billion years ago. Why is it so difficult to go back any further?

171. #171 chelle

     September 18, 2012

     DavidL,

     “Why do you think there are regions in space where this law is violated?”

     Yes of course there is a gravity connection between those 2 points in the case of A, I expressed myself badly. What I should have said is very weakly. But you see in those canals gravity adds up, while over the wide open space there is no (or I should say very little) mass that maintains a connection while it is the case within those canals; linked vs. (almost) unlinked.

     ” … the standard model comes up with a pretty good estimate.”

     I guess you mean here the ‘Big Bang’ model, because The Standard Model (of particle physics) is something else. If you and your friends such as ‘Wow’ like to take the Big Bang as the reference for the evolution of the Universe, than you can do as you wish, just like I’m not holding you back from believing in any other well calculated fairy tale. You may keep on living in oblivion, for me the expansion of our own little universe (Solar system/Milky Way) in the giant Aether bath that the real Universe is, is more sensible. Anyway, it’s a free world, have fun!

     Chelle, it is not a question of believing. I am an Engineer not a Scientist, and as long as photons reliably behave like waves when I try to detect their diffraction paterns, and particles when I try to count them, what they actually are is irrelevant. As long as the appropriate analogy accurately predicts their behaviour, and does so regardless of which way they are moving through any Aether, then.any paradox only seems to result from the failure of your extrapolated metaphor to describe reality. You therefore conclude it is reality that has a problem!

     From your previous posts you seem happy to accept a fixed universe where gravity somehow manages to constrain matter within an array of “knots” connected by “canals” Odd indeed that you are postulating that the only place in the universe where there is any expansion* is in our tiny insignificant galaxy that is but a small subset of our “knot”. The one region where we know for certain that gravity has been winning for the last 4.5 billion years at least, and where speeds can be inferred from distances measured by parallax without any knowledge of redshift.

     DavidL,

     “I am an Engineer … what they actually are is irrelevant.”

     Of course that’s your job as an engineer, to apply the math and that’s it. If you want to measure how fast a car is driving, you only need a few measurements and you can figure out a lot of things, there is no need to bring the actual car into the picture, it all works on paper.

     “Odd indeed that you are postulating that the only place in the universe where there is any expansion (objects moving apart in a fixed space) is in our tiny insignificant galaxy that is but a small subset of our “knot”.”

     I’m not postulating that there is an ‘expansion’ only in our Milky Way.

     First of all the Milky Way is not expanding, because gravity is keeping it together, this is something we all agree upon. Second, when I say that we (Solar system/Milky Way) are expanding in to Space, than I’m speaking about the light we emit, and the gravity that stretches out into space. See it as putting a heating element in the middle of a swimming pool, the longer you have it emitting heat, the wider the pool gets to be warmed, affecting incoming light. So the heating element isn’t expanding but it’s ‘influence’ within the medium is expanding. Now incoming light would start to show some scattering effects, but something like a torpedo (wave-particle) would keep it’s straight line towards the heating element, but have a different property than when the water would have had a constant non gradient temperature level.

     “First of all the Milky Way is not expanding,”

     Perhaps we are getting somewhere at last. It helps if we speak the same language. When you say that our galaxy is expanding, you simply mean it is broadcasting its presence to the rest of the universe. Perhaps you should pick a less ambiguous word, but I’m okay with that concept. and also that we can observe the rest of the universe broadcasting in a similar manner.

     So do you think there is any real expansion(i.e physical objects getting further apart) going on and if so where and why when gravity should prevent it?

     Can you explain the source of the redshifts we observe (light wavelength apparently increasing, not simply getting dimmer) and its apparent correlation with the distance of the light source from us?

203. #203 chelle

     September 19, 2012

     DavidL,

     you simply mean it is broadcasting its presence to the rest of the universe.

     Yes.

     For the rest you can look at the Universe as one giant static aquarium (Aether), with canals of gravity in them, where clusters move in all directions. And the longer we ‘broadcast our presence’ in the aquarium, the more we heat up the water around us, so light that comes from further away and gradually get’s to be ‘hit’ earlier and earlier by our ‘field’, and so it starts to shift more and more over time, we aren’t a static entity. You also have to remember that there once was a day that we weren’t born and emitting light.

     btw how fast would a signal be ‘traveling’ from one side of the Universe to the other, through those canals, thanks the gravitational tension in that web-construction, just like how a spider reacts and catches it’s pray when a web-wire is only slightly triggered: http://www.bbc.co.uk/nature/18990161

     It’s not a problem of what you believe in. It’s the problem of you pretending it’s some form of science. You haven’t provided any evidence for any of it. Thus, that makes it pseudo science.

     Let’s do this small steps at a time to see where we are agreed. Firstly regarding your comment to Wow, can we agree that “the speed of light has never been observed to be affected by the Aether”?

     So, a couple of simple questions.

     Do you think there is something special about your canals such that gravity within them is fundamentally different to gravity between them?

     Are you trying to say that you think redshift is due to photons coming to us interacting with those we are radiating out?

206. #206 Wow

     “can we agree that “the speed of light has never been observed to be affected by the Aether”?”

     Yes, but not in reverse, the state of the Aether could affect the speed of light, e.g. Red Shift.

     “Do you think there is something special about your canals such that gravity within them is fundamentally different to gravity between them?”

     Of course, that’s what I have been saying all the time, look at my comment on September 12, 5:09 am. Gravity itself is the same surely, but putting elements in a line causes them to add up. See, A pulls on B, B pulls on C, so when A pulls on B it also pulls on C. It’s about connectivity. But not only does A pull on B, A also pulls on C, and etc. … this way you establish a strong connection just like the wire of that spider. Or when you put one layer of epoxy over the other, it all adds up and strength increases, making very tense canals, and structures.

     “Are you trying to say that you think redshift is due to photons coming to us interacting with those we are radiating out?”

     Yes but not in the sense of the old Tired Light hypothesis. Light that moves through the Aether, sucks energy out of the Aether, so the tension within the Aether becomes slightly smaller and thus light moves slightly slower and loses some energy. So on Earth we all are bathing in the same Aether temperature and light is constant, but if you go very far in to space you get a small difference.

     No, it is the overall tension in the Aether that drops. Imagine planting a bunch of threes who all cast a shadow, than the ground temperature drops. It is also how gravity works like ‘david’ repeated what Galileo said: “eppur si muove”, to generate gravity you need to have your particles moving. The tension of the Aether always moves towards; the shade of the particle/low pressure/empty container. To keep it’s empty spot it needs to keep on moving forward, to keep it’s shade. Just like Hilbert’s paradox of the Grand Hotel, or how a horse chases a carrot:

     The particle needs to keep on rolling forward to maintain it’s empty space.

     “Could you imagine a universe where the threshold would be lower,”

     Absolutely. This could probably happen close to a plane in the Aether where a thin layer of Kryptonite was sandwiched between two graphene films, but investigation of this hypothesis must wait until we find an area of space radiating light showing the strong lines of the absorption spectrum of Kryptonite.

     Meanwhile, the expansion of the universe and the redshift are explained by NORMAL science (as opposed to post-normal or ab-normal) with something called “The Doppler Shift” and is the result of ANY wave emitted from a source moving in relation to an observer.

     “Can you prove me the Expansion of Space besides using the Red Shift that I could equally use to prove the Existence of the Aether.”

     I am not in the business of proving anything, nor is any Scientist. Only mathematicians do that. Scientists try to explain observed phenomena, and make predictions based on their acquired understanding. I am not asking you to prove anything either, merely to explain the red shift. My explanation is that the red-shifted objects appear to be moving away from us. This does not require expanding space. By regarding the Big Bang as a huge conventional explosion hurling galaxies through the Aether, the Doppler effect will generate a red shift as well: indeed I suspect that 95% of people who are aware of the concept of the Big Bang would explain it this way if asked. If this was your hypothesis, we could pursue how to distinguish between the two possibilities. But your static universe precludes this mechanism, so the next step is to examine your explanation for the red shift to see if it we can fit it into known physics with only small changes

255. #255 Wow

     September 19, 2012

     Except the aether, being the medium of transfer for this hypothesised light is moving too. Which means that if it were a conventional explosion, we would be able to tell who is at the center of the universe because only those still at the centre see retreating aether in every direction.

     Anyone NOT at the center and unmoving from it would see anisotropy as aether “nearer” the point of explosion coming toward them faster than the aether further from the explosion is going away.

     Either our planet on the edge of the milky way “happens” to be at the single point at the exact centre of the big bang (why did the rest of the milky way get shafted on this special position? And what happens as we rotate around the Milky way? We’d no longer be AT the centre, so it would be a double cooncidence that we happen to be at this point ONLY when we’re able to note it), or there is no aether.

256. #256 chelle

     September 19, 2012

     DavidL,

     I am not asking you to prove anything either, merely to explain the red shift.

     I already did so in my comment at 2:26 am:

     First of all the Milky Way is not expanding, because gravity is keeping it together, this is something we all agree upon. Second, when I say that we (Solar system/Milky Way) are expanding in to Space, than I’m speaking about the light we emit, and the gravity that stretches out into space. See it as putting a heating element in the middle of a swimming pool, the longer you have it emitting heat, the wider the pool gets to be warmed, affecting incoming light. So the heating element isn’t expanding but it’s ‘influence’ within the medium is expanding. Now incoming light would start to show some scattering effects, but something like a torpedo (wave-particle) would keep it’s straight line towards the heating element, but have a different property than when the water would have had a constant non gradient temperature level.

     –

     By regarding the Big Bang as a huge conventional explosion hurling galaxies through the Aether ….

     The ‘proposed’ Big Bang doesn’t work like that, it isn’t like a fire cracker …

     –

     the next step is to examine your explanation for the red shift to see if it we can fit it into known physics with only small changes …

     I don’t know what’s going on, but I’ve been explaining all this in many comments now; the excitement of the Aether gradually changes, over distance, over the time that we have been sending out energy, light and gravity into Space, since our galaxy and solar system was born. So the ‘only small change’ you need to embed into the program is an expanding temperature (excitement) gradient of the Aether around us, that’s it.

     Chelle:
     

     For A there is no gravity connection between those 2 points, while for B there is a strong connection. So it can’t be that they all are moving away at the same speed from each other, and certainly not away from us, all in the same direction, away from us.

     Ah, I think I get what you’re saying now. Your mistake is thinking that the statement “objects move away from us faster, the further away they are” is an ironclad rule that all objects follow, rather than a general trend.
     You are right: if every single object obeyed Hubble’s law with equal and high precision, that would mean that gravity is having no effect. But they don’t. Take a look at the Wikipedia page for Hubble’s law. See the graph about 25% down the page, on the right? You’ll notice that not all the points fall on the line. In fact, very few of them fall exactly on the line. The differences are due to gravity.

     Now granted, this is a relatively simple and small data set, but the argument above holds for more comprehensive data sets too. We do not observe every single object obeying Hubble’s law with equal and high precision. The difference between the line and the points are generally due to gravity (though, since IANA cosmologist, I will hedge and say there may be other effects I don’t know about).

     Don’t know if that’s ‘my’ mistake, on a local scale this is the case because gravity does hold things together.

     No, my real giant mistake was using that image to start with. I thought that it was in analog with the exact position of the Stars, as Ethan talked about the ‘Giant Superstructures in our Universe’. If someone had pointed out that it wasn’t a real image based on the distance of all the stars around us, than I wouldn’t have made a fool out of myself. So there are no such structures in Space, or are there? 

     So what are those millennium images actually showing; contractions of matter (gravity) with an additional ‘constant’ force of expansion … but than again you say that according to real measurements it is rather ‘a general trend’ than a ‘rule’.

For Expanding Space to pull the matter within it along, that overrules Gravity, that space needs to apply an attraction force on matter to pull it along, otherwise ‘Space’ is just flying by, or does each piece of matter has a ‘given’ expansion *factor* within itself?

     Actually, it’s neither.

     Deniers of AGW get this wrong all the time.

     There is a trend. Individual motions are imposed upon this trend. The resulting summation for any one object is the redshift seen.

     By collecting the redshift of many galaxies of approximately appropriate distance, an averaging of their redhift should cancel out any motion imposed upon the motion imposed by expansion.

     Chelle, “z” is not a unique value. And Z is not the value of expansion of space. I don’t know why you think so. Z is a measure of redshift to a given object. For one star or galaxy or supernova or whatever it has a certain value, for another it has a different one.
     z=observed wavelenght – emited wavelenght/emited wavelenght

     From the formula you can clearly see that this has nothing to do with whole universe. Nor that it’s some sort of constant.

     No it’s not! From what do you gather that??? You have the same frame rendered with different redshift clearly showing the effects of it. You see the same structure but with redshift of 1, 2, 6 etc.. and you can clearly see how clusters become less and less prominent as the redshift increases. How can you say it’s constant when in one image it’s z=1 and in other z=6? Do you know what constant means?

     Z is in each frame of the simulation (0,1,2,6) the same for ALL the objects. So it doesn’t seems like every object has a different value like you first said, and if so, than there ‘is’ some sort of constant.

     Perhaps better would be saying that all the objects have the same Z-value, so how is the difference in distance for each object (Expansion vs. Gravity) embedded into the program?

     September 20, 2012

     Chelle,

     objects don’t have z-value per say. Mhm.. how to put this so you understand. Ok, let’s forget the millenium simulation for a bit. Let’s downscale it just for the sake of argument and simplify it. Now don’t stick to the following explanation to strictly cause the values aren’t the same, but the concept is.

     Let’s say i have a light bulb 1 meter from me and i measure the incoming spectrum. I get a certain expected value. Now, let that lightbulb move away from me and I measure the spectrum again, i notice the colors have shifted by a certain amount. That amount is called a redshift (or blueshift if it’s moving towards me). That’s the “z” value. The faster it moves away, the bigger “z” value will be. Remember, emited wavelenght and observed wavelenght. The lightbulb is the same in both cases. It doesn’t have it’s intrinsic z-value. I, the observer, measure the value. The object measured doesn’t change any of it’s properties. It still emits the same light the same way, the speed it moves away from me dictates the “z” value. If it moves i.e 50m/s from me i might get a “z” value of 1.75. If it moves away 250 m/s, I might get a value of z=3.5 and so on.

     Now, to the milenium sim. Each rendered frame with different “z” value shows what the observer sees. Observer being the camera or you/me looking at the clusters. The clusters don’t change. Our view of them changes.

304. #304 DavidL

     September 20, 2012

     To busy to catch up with this thread or think this comment through, but my understanding was that the z value is effectively the “time axis” of the simulation, with z proportional to both elapsed time and cosmological expansion rate. I’m prepared to be told I got that completely wrong though!

305. #305 chelle

     September 20, 2012

     Sinisa,

     Thanks for your explanation, although it is not very different from my example where I used a dimmer to turn down the lights. As you turn down the dimmer over time, Stars seem to be moving further away. In a fixed matrix with each solar object at the same distance and same mass your example will work perfectly.

     Now let’s look at the Millennium Sim:
     http://www.mpa-garching.mpg.de/galform/millennium-II/Images/evol_12panel.jpg

     • Here you start with a situation at the bottom, where there Z=0 this means that all is Static, is that correct?
     • Next have all the objects ‘race’ away from each other at a set speed Z=0.99 it is all clear. But now my question is again how is the difference in distance for each object (Expansion vs. Gravity) embedded into the program? Some objects should be hold back more than others due to gravity. And a ‘knot’ in that structure should slow down the expansion rate ‘Z’ in that tight place because it is also the case in our Milky Way, Gravity slows down the Expansion, so Z can not be the same everywhere. Here I also like to again add a previous question:

     For Expanding Space to pull the matter within it along, that overrules Gravity, that space needs to apply an attraction force on matter to pull it along, otherwise ‘Space’ is just flying by, or does each piece of matter has a ‘given’ expansion *factor* within itself?

     If so, than that ‘expansion factor’ needs to be embedded into every atom that makes up a cluster that includes you and me, but if our Milky Way is holding it together than how can it all be expanding, how does that work?

     What you now should do is have a look at the link that I’m posting in my next comment, and see how the Universe and it’s Red Shift really looks like, and you’ll see that there is a more circular ripple pattern around our position as if someone had drop a pebble in a pond, so it all looks more like a Little Bang / Blast that we created, than stuff expanding in ALL directions all over the Universe.

     @ Chelle

     “although it is not very different from my example where I used a dimmer to turn down the lights”

     it’s very different, since you are changing the intensity of the source. This is not what happens in space. The source needs to stay the same, hence the need for standard candle and type Ia supernova.

     “In a fixed matrix with each solar object at the same distance and same mass your example will work”

     Like I said, the lightbulb example is simplification, but there is no need for fixed matrix (don’t even understand to what matrix you are reffering?)

     “Next have all the objects ‘race’ away from each other at a set speed Z=0.99 it is all clear.”

     No no no! “z” is not a measure of speed! The example with lightbulb shows just what “z” is. But in space the redshift is NOT CAUSED by the speed of galaxies or clusters themselves. It is caused by the metric expansion of space. Or in other words, the redshift is not caused by speed of galaxy but by property of spacetime. This is a huge difference and extremely important one.

     “But now my question is again how is the difference in distance for each object embedded into the program?”

     I can’t answer this question since I didn’t program the simulation. But you need to understand that redshift is not a measure of distance. Distance is measured by i.e. measuring the brightness of the source, redshift gives the spectrum of the source.

     “Some objects should be hold back more than others due to gravity”
     this is true and in no way is it broken in the sim.

     “also the case in our Milky Way, Gravity slows down the Expansion”

     No again! Gravity doesn’t slow the expansion. Expansion is a property of space, gravity causes the objects that it “attracts” (to use newtonian term, altough not really true) to stay relatively together. i.e. the forces holding molecules and atoms of your body together don’t cause the gravity to attract you less towards the center of the earth. It’s just the case of which one is a stronger force for a given scenario. This is actually elementary school physics… adding vector forces together or subtracting.

     “, and you’ll see that there is a more circular ripple pattern around our position as if someone had drop a pebble in a pond”

     that’s the image from sloan digital survey. That has nothing to do with millenium sim. Why are confusing yourself even more? Millenium sim deals with replicating the obervation, and so far it does very successful job. The image you posted from sloan is direct observation of our local cluster. The whole point of millenium sim. was to try to replicate sloan’s survey. And it did.

     “looks more like a Little Bang / Blast that we created”

     Say what? We created? What in the world are you talking about. If someone from i.e. Andromeda galaxy did the survey they would get the same image. Then “they” created it and not us? Don’t you see the issue with that line of reasoning.

     It seems to me that expansion is what confuses you more than redshift. So let me quote wiki:
     “The metric expansion of space is the increase of distance with time between distant parts of the universe. It is an intrinsic expansion—that is, it is defined by the relative separation of parts of the universe and not by motion “outward” into preexisting space. ”

     Note the last part… NOT BY MOTION OUTWARD into preexisting space. The galaxies are not mowing away somewhere where there is space yet they haven’t been there. The space is expanding, in a way, onto itself.

     You are saying all the time that I am crazy, but this makes absolutely no sense at all, but ok.

     Anyway an other thing is how can you have a shift of a Wave when you have no Medium, it is the speed in relation to the medium that causes stretching or compression, it is so for water or sound-waves traveling through the air; but when you have no medium each particle that is emitted should be exactly the same.

     Regarding that other picture, nope if you had it taken from an other galaxy, the blue area would be around that galaxy, and not ours, and the circular ripple pattern also around that pov, and no longer around ours, that what I mean with Little Bang/Blast, we are blowing stuff all around, and that’s how you generate such an circular pattern.

     “Anyway an other thing is how can you have a shift of a Wave when you have no Medium”

     Do you know ANYTHING about electric fields and magnetic fields and the motor rule?

     Here’s a potted version:

     A changing electric field causes a magnetic field. A changing magnetic field causes an electric field. Therefore the changing electric field of a photon causes the projection of a magnetic field. That causes the projection of an electric field. And that is the photon.

     There is no medium.

322. #322 Wow

     September 20, 2012

     No, The Michelson–Morley proves that motion does not influence the the behaviour of light (in the Aether), and so it proves that Red Shift is no valuable proof for Stars that would be moving away. There is only proof that Gravity causes a Red Shift and Einstein spoke about GR as a *new* Aether. 

     Ergo what this all proves, is that the Stars aren’t moving away and are relatively static, and that it is an *effect* caused by the continuous expanding change of the state of the Aether around us, and this picture proves it:

     You can prove doppler shift with light.

     It is inherent to the idea of a wave that this be true.

     Gravity, however, leads to the proof that light is a particle, since you have to accelerate THE MEDIUM to get a frequency shift and this would NOT be the same change as you get with real GR shift.

     The key components of Feynman’s presentation of QED are three basic actions.
     • A photon goes from one place and time to another place and time.
     • An electron goes from one place and time to another place and time.
     • An electron emits or absorbs a photon at a certain place and time.

     “Sure a pulse will expand or contract like for a radar gun, but not the energy of the photon itself.”

     Chelle, you really do need to sit down and spend some time contemplating the chasm between what you think you know and what you actually know.

     A radar pulse returned from a moving target will indeed be longer or shorter than the transmitted one. Clocking a flat out Bugatti Veyron should change the pulse width by about one part in a couple of million. If you know a way to measure this I would be interested professionally. A Doppler radar measures the frequency change of the returned signal. I can assure you that energy of the returned frequency shifted photon is not the same as that of the transmitted one. The energy is directly proportional to frequency, but don’t take my word for it, use this calculator

     http://www.1728.org/freqwave.htm

     Invalidating these results would not be “a small change” to existing Physics. It would blow the heart out of EM theory, Quantum Mechanics, even the Quantum Electrodynamics you linked to above. You are ether the greatest scientist that has ever lived or wrong. Which do you think it is?

     So you think that a green apple becomes more blue when it is thrown to you, and more red when you throw it away? Now why don’t we film it, and compare colors at equal distances, so we are sure that we aren’t measuring the intervals in distance which may influence frequency and wavelength, just the color spectrum of the photon that comes of the apple. Now that shouldn’t be a hard thing to do, and no it wouldn’t change the hearth of science, only just very maybe that of the Big Bang theory. 

     p.s. I do graphics and computer simulations, but indeed might start to live from the state because economics is slow lately.

     As I said in my above post, I not only think that, but I have earned a considerable amount of money by measuring the “colour” change, albeit at 3 orders of magnitude lower in frequency.

     If you knew much about graphics you would realise “filming” it would be of no use as cameras measure only the relative amplitudes of the three primary colours. Observing the effect would require a spectrometer. Not my area of expertise, but I am confident if you put your apple on a rim of a platter, spin it fast enough, illuminate it and give me a spectrometer on an optical path tangential to that rim, I could tell you which way the platter was spinning from the spectrum of the reflected light alone.

     “..but indeed might start to live from the state because economics is slow lately.”

     Good to see reality impinges on your life somewhere.

     You might be right, but I think your own money making precision measurements are based on interval. Usually ideas like this have already been tested so let’s look if we can find a paper on it; if not, let’s look for someone who could do this rather simple test, so we know for sure if you’re right.

     I’m not sure if that comment is about Doppler radars or spectrometry.

     If the former, are you seriously claiming that if I design an electronic circuit to multiply two analog signal together and measure the frequency of the resulting signal , what I get when I build the circuit is something that will magically measure an “interval” instead? Sort of like Marconi switching on his first prototype radio and being amazed at the picture quality. What a strange world you live in.

     If the latter then it is not something you are likely to find a paper on. It’s not cutting edge Physics, just a common sense demonstration of the same principle as getting caught by a radar speed trap. The only difference is that frequencies in the visible spectrum are way too high to process with current electronic technology so completely different measurement methods are required. And of course there is no “interval” to measure in this case. An apple may appear at regular intervals, but adding more apples or changing the diameter of the platter would yield the same result if that interval varies. The frequency shift will always be related to the SPEED of the apple with respect to the spectrometer

     You might be right, but I think your own money making precision measurements are based on interval.

     I’m not sure if that comment is about Doppler radars or spectrometry.

     What you do with your Radar gun, is similar to trowing every second a ball into one direction, now the speed of an incoming wall/car will defined the amount of balls that get to be bounced back within one time period, and this defines the speed of the car, so it’s dependent on the interval of the signal you send.

     What I’m saying is that you should trow one ball from that incoming wall/car and be able measure the speed of the car and the Doppler-effect, just like in the case of a moving ambulance, and this is something what you can’t do because the speed of light is constant, and the emission of a photon instant (QM). So it would make no difference if the apple was moving away, standing still or moving towards you at the time of emission, so there is no Doppler-effect observable and the Apple will keep its green color, there will be no Shift, and the same goes for Solar bodies that are moving away, you need to send a signal towards them at a set frequency and calculate the rebound, to measure their velocity. That’s how things in the real world work.

355. #355 Wow

     “What you do with your Radar gun, is similar to trowing every second a ball into one direction”

     Nope. What he does with his radar gun is show the change in frequency when the signal reflects off the target.

     This is the Doppler Effect.

     Chelle the world must seem really unfair to you. You must look out with dismay to a world full of Scientists and Engineers who achieve the most wondrous things despite being total idiots who don’t have the remotest idea how anything works. And not one of them has ever thought to tap your genius

     A few years ago I watched with interest as a whole group of these idiots working for the European Space Agency sent the Cassini spacecraft to Saturn carrying a little probe called Huygens to land on its moon Titan. The little fellow could not talk to earth by itself, so Cassini would relay his messages back to earth. So they gave the little guy the radio equivalent of a blue light to flash at “mum” and gave “mum” a receiver that could only see blue light (keeps the noise out) And do you know what these idiots did? They forgot about the Doppler Effect. Doh! Fortunately, just in time a couple of them realised that when junior set off on his own, accelerating towards his final rendezvous, his blue light would begin to turn a bit purple, and pretty soon mum would not be able to pick up a word of what he was saying. The fight plan was modified mid mission and the idiots succeeded spectacularly.

     Check the wiki link below, especially the paragraph “A critical design flaw resolved” and tell me how you would have saved the mission

     Chelle,

     Yes, the apple really is redder (or greener) depending on the relative velocity between you and the apple. That’s what the doppler effect is all about. Consider an object that appears to be yellow to a comoving observer. That object might well appear to be red if you and the object are separating fast enough. It may well appear to be green if you and the object are approaching each other rapidly enough.

     So what color is the object really? I guess you could say that the object has a “proper color” (analogous to concepts like proper time and proper length in SR) of yellow. However, relativity (you know, proposed by that Einstein guy you’re fond of quoting) says that there are no preferred reference frames. Therefore, the object “really” is yellow AND green AND red, depending on the reference frame of the observer. Color is indeed a relative notion, not an absolute one.

     I realize that this seems odd, but that’s mainly because the speeds involved with making an object change its observed color are higher by far than any speeds ever obtained by human observers.

359. #359 Chelle

     September 21, 2012

     Wow,

     “This is the Doppler Effect.”

     Yes, that is the Doppler-effect, but first he needs to set up a medium with intervals, between him and the moving object. Just like sound-waves have a medium between the ambulance and the listener. The speed of sound is based on the interval between the molecules that make up the ‘air’. No air no sound waves; no generated radar signal no Doppler-effect.

     –

     DavidL,

     For Huygens it is the same thing, the radio signal is set, of course when you move relatively of that signal in-between its intervals you have a Doppler-effect, just like when you would have wanted to catch those balls that are thrown every second, if you drive too fast you they might come to fast for you to process them.

     So again for measuring the speed of those distant galaxies you need to set a signal, and relative to that signal you can measure the speed of the moving object. For the Hubble Red Shift, you only get a change in energy of the incoming photons, and that is not enough. It’s like getting back one ball that is colder, when you know that when it left it had a set temperature, the only thing that could have happened is that it got to be cooled down along the way.

360. #360 Chelle

     September 21, 2012

     Sean T,

     That’s wrong because let’s say that the speed of light is constant in a vacuum, and absorption and emission of a photon by an electron is instant (QM), so there is nothing changing in-between, unless you change the speed of light.

365. #365 Sean T

     September 21, 2012

     chelle,

     Nothing in the doppler effect has anything to do with changing the speed of light. Simple physics: the speed of light = the frequency x wavelength. When an object is viewed by a moving observer, the frequency depends on the relative motion of the observer and the object. The wavelength also depends on this relative motion. The product of the two is invariant; that’s what started Einstein on special relativity to begin with. The speed of light is the same in ALL reference frames.

     Now again, more basic physics: a frequency measurement is really nothing more than a time measurement. Frequency is simply an inverse time. A wavelength measurement is of course a distance measurement. Special relativity tells us that the speed of light is constant no matter the relative motion of the source and observer (at least in inertial reference frames). Since frequency is really time and wavelength is distance, the doppler effect for light is nothing more than a manifestation of length contraction and time dilation, as spelled out in any good text on special relativity. I suggest you read about these before rejecting the doppler effect.

366. #366 Sean T

     September 21, 2012

     Chelle,

     Just a quick quiz for you: Let’s assume that you and I meet somewhere and set super-accurate timers to zero. After this, we leave our meeting places with two different velocities, Vs and Vc. We start our timers at the same time as we depart. We both then observe a flash of light from an assistant. When we compare our results, I say that the flash of light occured when my timer read ts, you say it occurred when your timer read tc. Question: at what time did the flash of light REALLY occur? Who’s time is the right one?

367. #367 Sean T

No air no sound waves; no generated radar signal no Doppler-effect.

     Chelle, I already explained this to you either way up-thread or in an earlier thread. Photons are not acoustic waves; their wave-like nature is not due compression/energy transfer between adjacent particles. We use the same word “wave” for both but they are different phenomena. They are not just like sound waves. Thinking they are like sound waves shows how little you know about the subject.

369. #369 chelle

     September 21, 2012

     Sean T,

     You could look at the Doppler-effect that DavidL has for his Radar, and in the case of Huygens, basically as that ‘flash of light’ that you mention in your little quiz.

     When you set a timer for it to *flash* every second, and you have a mirror that moves; than you know when *flashes* comes back at an interval speed of 0.8 sec. and next 0.6 sec., that the mirror is accelerating towards you, because the intervals or frequency becomes smaller, and this is like how you explain, “nothing more than a manifestation of length contraction and time dilation.

     But now comes the difficult part of the Doppler-effect and Red Shift of galaxies in Space; and what I would like to hear your opinion on, is how much time it takes for a *flash* of light to emit one photon, that is caused by this QM effect:

     In physics, emission is the process by which a higher energy quantum mechanical state of a particle becomes converted to a lower one through the emission of a photon, resulting in the production of light.
     http://en.wikipedia.org/wiki/Emission_spectrum

     I presume that the emission of a photon is instant, because Electrons jump from one QM state to an other just like that, or am I wrong here?

     If I’m wrong, than could you please tell me how long it takes, because than you would indeed have a similar situation as when setting a frequency (time interval), by lighting your *flash* every second. And a photon would become longer when you move away from me, and shorter when you move towards me, but if a photon is ‘born’ with its wavelength ‘set’ instantaneously, than it won’t change after that. You see when a photon is generated there is no time involved, the length of the wave is embedded within one photon, or not?

     The same goes for the absorption process that is instantaneously. So it’s not like a Radio signal that you give a pulse (frequency), and yes such a signal can than have a Doppler-effect, but not those who are made by Electrons jumping from one QM state to an other, and if I’m correct, it are exactly those photons that generate the Red Shift.

370. #370 Wow

     That isn’t the doppler effect.

     The doppler effect changes the frequency of the light.

     eric,

     “Chelle, I already explained this to you either way up-thread or in an earlier thread. Photons are not acoustic waves …”

     Sigh, I was referring here to how the Radar signal set’s a field with an interval (frequency) just like how air has an interval based on the distance between the molecules … If you make a sound than it travels depending on the speed of the spacing between the molecules if you make a sound while moving forward you are adding compression. In the same way if you have a mirror that stands still that bounces back the Radar signal, the bounced back signal could travel supposedly at same frequency (interval) of that send out Radar signal, now if the mirror moves towards you, than things starts to change and you get a Doppler-effect, the send out Radar signal becomes compressed.

372. #372 Wow

     September 21, 2012

     “and what I would like to hear your opinion on, is how much time it takes for a *flash* of light to emit one photon”

     http://www.pmrinfosolutions.com/process1/…/24…7…/po-7-10-491.doc

     150 picoseconds is common. But some take much much longer. The metastable state that is the basis of measuring time takes milliseconds.

     There is simply no time between the discrete levels. It is either State A or State B, there is nothing in between, not even time. Yes it might take a long time before A goes to B, but when it does, it takes no time. 

     So now tell me how those emitted photons could be stretched over time e.g. in wavelength, when there is no time to be stretched?

     ” It is either State A or State B, there is nothing in between”

     Yes there is.

     No, if there was, there would be something between A and B and there isn’t anything in between. Sure when you have two electrons you can get an ‘AB’, but the basic photon that jumps from A to B is discrete and can’t be stretched it is a closed quanta. So yes in a two electron set up you can stretch time as long as you like, and generate some shift, but the individual quanta generated  by one jumping electron can’t be stretched by motion of the Atom, also because of the discrete limitations of possible states within the Atom. If what you say is right, than Atoms could stretch out into space, Wow!

     If it could be stretched than you would measure values in-between A and B and there are none, the Energy-levels are discrete. Let’s say that a photon is stretched, than you still aren’t measuring any difference because you only have discrete measurement results, that’s how you know.

     –

     “If what you say is right, than Atoms could stretch out into space”

     They do.

     What you are saying with your Expansion theory is that Atoms are bound together within the Milky Way by gravity and all the other forces, but once outside the Milky Way everything can stretch. But even more unique, is that according to you it is still possible that those generated photons can be stretched over time within those Atoms who aren’t stretched by Expanding space. Mh, that’s a strange situation. So please tell me what is Expansion actually doing within those atoms, when photons generated by electrons jumping from state A to state B are created. btw in those stretched photons there is nothing keeping them together; one part just moves further away from the other when they fly towards us, and not one part is flying faster than the other so what time do these photons have within them, I guess none, so what is there to being stretched?

390. #390 David L

     September 22, 2012

     Chelle. I think am beginning to understand at least one of your comprehension problems, so I will have one last go to try to establish if you come here out of a genuine desire to improve your understanding of physics, or you just regard this blog as a platform to tell everybody else how utterly wrong they are about everything. You seem to be either conflating or totally misunderstanding two characteristics of EM radiation: the (temporal) length of a “flash” and the frequency of the EM radiation in it (and a “flash” is almost always many many photons)

     The first radars, and many today, operate by transmitting a pulse of energy and measuring the interval to the return. The pulse is as narrow as possible, both to save power and allow more accurate measurement of the echo. This allows you to measure range if you know the speed of light. If you repeat this process you can derive the speed of the target from the rate of change of distance, exactly as you tried to explain the process in one of your earlier posts. The rate you repeat the process at is known as the pulse repetition frequency (prf), but the energy is transmitted at the carrier frequency (CF) In audio terms, this is similar to saying the equipment plays Middle C for a second and repeats this every 20 seconds. But within the one-second note, the sound pressure wave is reversing 524 times. Are you clear on that concept, because from your previous posts you should disagree with none of this?

     Now it is possible to build a radar trap based on this, (and laser speed traps operate this way for reasons not relevant here) But by definition Doppler radars designed to record speed operate differently. Instead of timing the arrival of the return pulse, the equipment measures how its frequency has changed from that transmitted. In audio terms you play a one second note of 262 cycles of Middle C and get back 262 cycles of c# in 944mS. You might want to argue that the receiver is still measuring the intervals between each of the 524 individual individual peaks. Strictly speaking this could possibly be true, but it is not the interval you originally meant, and it is simpler to process the signals in the frequency domain rather than have to make precision timings.

     And by definition a photon can not pass a point in space in an instant. The property that distinguishes a red photon from a blue one is the number of times per second the EM field associated with it oscillates as it passes (Its frequency). As this is trillions for a visible photon it does not have to take long in human terms to pass and still show its true colour, but it certainly cannot be an instant.

     September 22, 2012

     DavidL,

     Yes, thanks that is a good summarization, and interesting stuff.

     I have to admit that I didn’t thought that it could be so refined, as a ‘color’ photon itself is a composit of tones, that can be more or less compressed. This is leaving me with my last jibber jabber, regarding the ‘single’ photon that you get from a Hydrogen Atom, that is generated by a single jump from a single electron and that should also be redshifted by the suposed Expansion of Space, how can you stretch such a thing out, and measure it?

     “I wonder where the hell you’re getting your crap from”

     I would say that one of them is Democritus, who posed hypotheses like:

     “The theory of Democritus and Leucippus held that everything is composed of “atoms”, which are physically, but not geometrically, indivisible; that between atoms lies empty space; that atoms are indestructible; have always been, and always will be, in motion …”
     http://en.wikipedia.org/wiki/Democritus#Atomic_hypothesis

     One can ask themselves; what is one light photon an how can it be stretched out by Expanding Space, where does Space get the force to do so and how has it got grip on those photons?

     When I have two boats moving from one side to the other, and I want to increase the Space between them, than the Space has to pull those two boats apart from each other, the space has to have grip on them, and apply a force to make those two boats lose energy, it either pushes them apart or pulls them apart, there is NO other way to move them apart, something has to act upon them.

     In the same way when an Atom emits a Photon it loses energy as the Electron in the Atom moves to a lower Energy State. So where does the Expanding space get’s the energy to push/pull those Photons apart, and make them lose energy; and where is the energy going considering that there are an (almost?) infinite amount of photons traveling through the Universe that are supposedly losing energy at this very moment.

     As always the Devil is in the details, and Occam’s razor-wise you end up with a building block of a theory, namely the expansion of a single photon, that is extremely dodgy.

     Dear Wow,

     Please answer the question, how can a photon be stretched out by Expanding Space?

     For change the tone of a note, you physically need to change something … even in the case of the Magic Flute you need to have a longer or a shorter tube. What is it you say that is physically pulling on the photon, how is it that Space has grip on all those photons who are moving around in ALL directions?

     … and why is that all the areas of Red Shifted stars point straight in our direction:

     Chelle, once again you seem proud to announce to us all that you understand nothing of what you read. The image you linked to is a false colour image. A sort of graph where colour is used to indicate the age of the galaxies. ALL the galaxies on this plot are red shifted, (the further from the centre the more red shifted). What other explanation can there be other than that they are moving away from us?

403. #403 Wow

     DavidL,

     “ALL the galaxies on this plot are red shifted, (the further from the centre the more red shifted). What other explanation can there be other than that they are moving away from us?

     This is what the picture shows:

     “Galaxies are colored according to the ages of their stars, with the redder, more strongly clustered points showing galaxies that are made of older stars. The outer circle is at a distance of two billion light years.”
     http://www.sdss.org/includes/sideimages/sdss_pie2.html

     Now look at the distribution of the Oldest Stars in Red, they form a very clear pattern of red ‘stripes’ that points towards us; or away from us, as if there was a splash.

405. #405 Wow

     September 23, 2012

     “This is what the picture shows:”

     So the colour is NOT their redshift. Just the age of the galaxy.

     And there is no red stripe as is obvious when you take away the white circle inscribed at the two billion light year distance.

     Oh, look. If you draw a circle around something, you get a circle…

     How amazing.

     Anyone who thinks there is one, try this:

     Crop the image so you don’t see the circle.

     The upper half has a sort-of circle very small and off to the left, but if it does exist, it has a “centre” well off the location of us. The upper half as nowhere anything at all resembling a circle.

     But then again, you can look at a tree and see a frowning face:

     No, just the splash of another turd idea from your fevered ego, chelle, into the sewer of crap ideas you love to splash around in.

     Earlier you claimed circles. Now they’re radials.

     Neither exist.

     Science is a method to stop us using what we want to see from becoming what we think is there.

     And mathematics, being created as a method of measuring the reality rather than the perception would give ZERO credence to the idea of radials pointing to us.

     A little edge detection to locate edges (a common trick used by the human visual cortex that enables us to see a complete picture despite our dual blind spot in the eye) and a collection of their length (to denote how much of a line there is) and the vectors (to find out where they point) indicate no significant linear component and absolutely no correlation with a radial toward the origin (to far far below 5% confidence).

     You would have a picture showing a face on a tree to be proof of ents.

408. #408 Wow

     September 23, 2012

     Oh, and there are no stars indicated on that graph. They would not show up at all at that scale and are indetectable as individual objects.

     Yes they do. I’ve added lines so you can see clearly how it matches exactly:

     http://tinyurl.com/Alignment-sdss

     In the third image I’ve displaced the radial array and nothing aligns any longer. I could keep on moving it around, but I can not get it aligned anywhere else because there is simply only one fit.

410. #410 Wow

     September 24, 2012

     Yes, if you draw lines radially, you will see radial lines.

     How much of each line is taken up by a spot of a galaxy?

     Almost none of it.

     And on the first four lines from 16h clockwise, the “lines” closest to it made by those galaxies DO NOT point along the vector of the line you put on there.

     All you’ve done is put lines on a picture that hasn’t got lines on it, then said “look! there are lines here!”.

     There are techniques of digital image processing that will eliminate your desired bias and TELL you how many lines there are, how long, and where they point.

     Chelle, from Ethan’s last post is is clear we have to stick to science or be banished to his dungeon. I will, and hope you can too. You ask:

     ” look at the distribution of the Oldest Stars in Red, they form a very clear pattern of red ‘stripes’ that points towards us; or away from us, as if there was a splash.”

     Firstly, it is undeniable that the image you posted shows EVERY galaxy we see is red-shifted. What other explanation for this is there other than they are moving away from us.? Tell us please in a way which won’t get you bumped of the thread. And unless you have a basic understanding of what the image means in its entirety, you can not possibly speculate about the cause of minor details.

     Secondly, I don’t know for sure what causes the stripes, but I can offer a couple of suggestions.
     1) They are an artifact of the resolution of the image and the jpeg compression applied to it in areas where there are more galaxies than pixels Only looking at the original data could remove this possibility

     2) Along any direction in space where there is a concentration of galaxies we would expect to see a stripe pointing towards us if the concentration is both moving away from us and spreading out. Older galaxies, coloured in red, will have been spreading out for longer, so will show as the longest stripes.

413. #413 chelle

     September 24, 2012

     DavidL,

     “Chelle, from Ethan’s last post is is clear we have to stick to science or be banished to his dungeon. I will, and hope you can too.”

     Can’t do, ’cause what I call science isn’t yet re-approved as science, so it’s slowly time to pack my stuff and move on.

     “Firstly, it is undeniable that the image you posted shows EVERY galaxy we see is red-shifted. What other explanation for this is there other than they are moving away from us.?”

     I’m not objecting that they are further away, I’m only contesting that they are moving away. I mentioned in my reply’s to you already a few times something like a ‘Little Bang’, I’m not going to repeat it here again, just do a quick search.

     –

     “Secondly, I don’t know for sure what causes the stripes, but I can offer a couple of suggestions.”

     I have just asked the question regarding these stripes to an experts from the SSDS-project, and I have taken the freedom to call you ‘a friend’ and included your suggestion. And I got a lightening fast a reply from Professor Weinberg, and it’s a rather cool explanation. So I’m posting it here along my own mail. btw bat’s (flitter-mice you find in dungeons), increase there intelligence by sharing information … Here’s the Q&A:

     Q: I’ve noticed in the the image of a “Slices through the SDSS 3-dimensional map of the distribution of galaxies.”, that the older stars in red, all have some sort of linear pattern that points towards the middle. I have highlighted this ‘circular array’ in the attached image. It looks a bit like they are splashed out from the center. (http://tinyurl.com/Alignment-sdss)

     So my question is, why is there such a pattern, and has it perhaps got something to do with visible limitations from our point of view, or are it dotted trajectories of the same Stars?

     A friend of mine suggested this as a reason:

     “Along any direction in space where there is a concentration of galaxies we would expect to see a stripe pointing towards us if the concentration is both moving away from us and spreading out. Older galaxies, colored in red, will have been spreading out for longer, so will show as the longest stripes.”

     I’ve learned that the ‘Expansion of Space’ isn’t like a real explosion and that Space more or less expands upon itself, therefor the confusion regarding this image, and me taking this opportunity to ask you as an expert.

     –

     Q: The red/orange points represent galaxies that are made primarily of old stars, and the green/blue points represent galaxies that are still actively forming young stars. “Passive” (red) galaxies are found preferentially in dense environments; astronomers are still trying to determine why this is so, but it probably occurs in part because these are regions where galaxy formation can start earlier and in part because hot gas between the galaxies can suppress star formation within them.

     When the SDSS makes a 3-dimensional map, it takes advantage of Hubble’s law, which says that a galaxies velocity is proportional to its distance: v = H_0 * d, where H_0 is Hubble’s constant. Hubble’s
     law is a consequence of the expansion of space, as you say in your message. We measure v, and infer d. However, Hubble’s law is not perfect, because in addition to velocities from the expansion of space, galaxies have “peculiar” velocities induced by gravitational accelerations in their immediate surroundings. These peculiar velocities cause an error in the inferred distance, making a galaxy appear closer or further than it really is.

     Because red galaxies live in dense environments with strong gravity, they tend to have larger peculiar velocities. Clumps of red galaxies therefore get stretched along the line of sight because of distance errors; these “stripes” pointing towards us are sometimes referred to whimsically as “fingers of god.” So your friend’s explanation is quite close to the mark — the difference is that what sets the red galaxies apart is their higher peculiar velocities rather than the longer time they have had to move.

     Well Chelle it is certainly cool that the good professor is prepared to give up his time to explain his work to you, and if you really have learned that the universe “expands upon itself” then we have made some progress, but I somehow doubt it because he is saying exactly what you have been told here for weeks. As he says, he is measuring red shift and inferring distance. I have no explanation for red shift other than that everything is moving away from us. Nor it seems do you, but you insist it is not moving away even though the professor’s data tells you it is. By far the best explanation for everything moving away is that space is expanding, a concept which you led the good professor to believe you already understood.

     And bear in mind it is a necessary consequence of his explanation that those whimsical “fingers of god.” would seem to point towards any observer anywhere in the Universe. It does not mean we are special should you think this is the real reason his explanation is cool. Alien Theologists in another galaxy will not be debating why their “fingers of god” are pointing to an outer spiral arm of the Milky Way.

     If you would like to read up on redshift space distortions and “fingers of God” in cosmology, they are well-known effects and google (and even wikipedia) will help you immensely, but this is not the place for that discussion: this page is.

     Wow:
     

     Ethan, may I just say that you’re fucking things up royally here letting chelle continue to spout her complete bollocks and ensuring that NOBODY learns ANYTHING.

     Personally, I learn interesting and useful information from many of the responses to Chelle. So I don’t mind his/her posts, despite the misunderstandings, because he/she tends to act (inadvertently) as a foil or ‘straight-man’ for other commenters.
     I actually mind yours more. Because while you may have useful insights, your machine-gun style of posting makes it extremely difficult to find any of the responses that might interest me. Instead, I end up scroll-wheeling over whole swaths of the conversation, and inevitably I miss something interesting.

     Chelle:
     

     how can a photon be stretched out by Expanding Space?

     As I understand it, photon magnetic and electic fields oscillate at a given frequency. If the space a photon traverses stretches ‘beneath’ it as it travels, then the photon will have oscillated fewer times in that space interval than it would have in a non-expanding space. In a sense, the photon traveled further during one oscillation than expected. Fewer oscillations per meter traveled = lower frequency = red shift.

     However, I could be wrong about that, so if there are any physicists around who want to correct me, be my guest.

423. #423 Wow
