The Power of Theory In Science

“He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.” -Leonardo Da Vinci It’s often lonely, these days, as a theorist. As soon as most people hear the word theory, in fact, they start thinking about something like this: But…

Defining the Big Bang

“As far as I see, such a theory [of the Big Bang] remains entirely outside any metaphysical or religious question. It leaves the materialist free to deny any transcendental Being. He may keep, for the bottom of space-time, the same attitude of mind he has been able to adopt for events occurring in non-singular places…

“We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.” -Stephen Hawking You’re probably familiar with the standard picture of our Universe. You’ve heard it all before: that the Universe we know of — stars, planets,…

Where is everybody?

“If the Universe Is Teeming with Aliens… Where Is Everybody?” -Stephen Webb As egocentric as we are, we know that not only are we but one planet of many orbiting our Sun, but that when we look up in the heavens, every point of light we see is another chance — another opportunity — for…

Dark Energy Confirmed Again!

“We all need to look into the dark side of our nature – that’s where the energy is, the passion. People are afraid of that because it holds pieces of us we’re busy denying.” -Sue Grafton No, not the dark side of our nature, just the dark side of nature! Because if all our Universe…

The Fun of Going Faster-Than-Light

“There is also an amplitude for light to go faster (or slower) than the conventional speed of light. You found out… that light doesn’t go only in straight lines; now, you find out that it doesn’t go only at the speed of light! It may surprise you that there is an amplitude for a photon…

The Fate of the Universe

Some say the world will end in fire, Some say in ice. From what I’ve tasted of desire I hold with those who favor fire. But if it had to perish twice, I think I know enough of hate To say that for destruction ice Is also great And would suffice. -Robert Frost Sure, if…

John Oliver: So, roughly speaking, what are the chances that the world is going to be destroyed? One-in-a-million? One-in-a-billion? Walter Wagner: Well, the best we can say right now is a one-in-two chance. John: 50-50? Walter: Yeah, 50-50… It’s a chance, it’s a 50-50 chance. John: You come back to this 50-50 thing, what is…

Einstein’s Last Mystery

“God does not play dice with the Universe.” -Einstein “Einstein, don’t tell God what to do.” -Neils Bohr (disputed, but awesome) Einstein, the brilliant mind behind general relativity and the concept of “spacetime,” is making the news again this week. As you all know, gravity isn’t some mysterious invisible force traveling across space, it comes…

“You still don’t get it, do you? He’ll find her! That’s what he does! That’s ALL he does! You can’t stop him!” -Kyle Reese, the Terminator Now that we’ve all survived Judgment Day, we can stop looking for ways to stop the Terminators, and go back to the search for dark matter. Let’s back up…
