Dark Energy

Category archives for Dark Energy

This is an enhanced version (with some upgraded images and text) of an article I first wrote over two years ago. It is just as valid today as it was back then, only today, I have a special offer to go with it. Next week, a bunch of cosmologists and myself are getting together and…

How Big is the Entire Universe?

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.” -Stephen Hawking The Universe is a vast, seemingly unending marvel of existence. Over the past century, we’ve learned that the Universe stretches out beyond the billions of stars in our Milky Way, out across billions of light years, containing close to…

A Dark Matter Deluge

“I soon became convinced… that all the theorizing would be empty brain exercise and therefore a waste of time unless one first ascertained what the population of the Universe really consists of.” -Fritz Zwicky Making the entire Universe isn’t easy. Even with 13.7 billion years of time, general relativity and all the known particles in…

Goodbye, Galaxies!

“I am undecided whether or not the Milky Way is but one of countless others all of which form an entire system. Perhaps the light from these infinitely distant galaxies is so faint that we cannot see them.” -Johann Heinrich Lambert One of the greatest discoveries of the 20th Century was that many of the…

“I have long held an opinion… that the various forms under which the forces of matter are made manifest have one common origin; or, in other words, are so directly related and mutually dependent, that they are convertible, as it were, one into another, and possess equivalents of power in their action.” -Michael Faraday For…

“Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before.” -Edgar Allen Poe Earlier this week, the Nobel Prize in Physics was announced for the discovery that the Universe is not only expanding, but that this expansion is accelerating! What does an accelerated expansion…

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 Ever since…

What the WMAP image means

“It has been rightly said that nothing is unimportant, nothing powerless in the universe; a single atom can dissolve everything, and save everything! What terror! There lies the eternal distinction between good and evil.” -Gerard De Nerval (For Rich C. and Sili, for their questions on this post.) The humble hydrogen atom — one proton…

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 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…
