Composition of the Universe

A fascinating talk about the composition of the universe [Youtube, approx 1 hour], presented by Sean Carroll, theoretical physicist at CIT. [via] His talk is fast-paced and high level, but has enough detail to get the imagination fired up. Topics include ordinary matter, the standard model, dark matter, dark energy, string theory, supersymmetry, and the expanding universe. The presentation is extremely coherent and easy to follow, even for non-theoretical-physicists such as myself. Enjoy.

UniverseNewsFilter: Scientists claim to have detected dark matter

UniverseNewsFilter: Scientists claim to have detected dark matter! Here are NASA's press release, feature page and multimedia presentation. For an explanation what dark matter is, I refer you to this page. After all that excitement, you can sit down and work out how much dark matter is in the Milky Way.

Good evidence that dark matter is for real.

Hmm....

Does dark matter exist? Dark matter has been suggested as a solution to the galaxy rotation problem where individual stars don't seem to rotate the way Newton's laws would predict. Now, some scientists are saying that observations fit with Einstein's general relativity, without any dark matter needed. I just find it amazing that no one has tried this yet.

Dork Matter.

Art from physics: it's a groovy gas. It's transonic flight. It's a pi-muon death cycle. It's a dark matter detector. It's a Super-Kamiokande with 9000 neutrino eyes. Dream on!

It ain't so dark anymore. Dark matter seems poised to assume its place among those astronomical phenomena that were predicted to exist before being observed. The planet Neptune and black holes to mention two of them. The last 100 years have really been a boom time for astronomy, and they're not slowing down.
