Dark Matter And Dark Energy Make Up 95 Percent Of Universe, Detailed Measurements Reveal
ScienceDaily (Nov. 3, 2009) — A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by Sarah Church of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University, and by Walter Gear, of Cardiff University in the United Kingdom. These measurements of the cosmic microwave background -- a faintly glowing relic of the hot, dense, young universe -- put limits on proposed alternatives to the standard model of cosmology and provide further support for the standard cosmological model, confirming that dark matter and dark energy make up 95% of everything in existence, while ordinary matter makes up just 5%.

In Krauss' talk I remember he said that ordinary matter and energy make up only 1% of the total. Guess he was a bit off there. The thing that most piqued my interest is his revelation that the universe could have come from nothing. I wonder if the last gap religionists have to shove their deity in will eventually be taken away from them as well.3. Comment #429686 by AMreasonedthinker on November 5, 2009 at 3:50 pm

The light from the early universe was initially unpolarized but became polarized when it struck moving matter in the very early universe.

There's a page eplaining CMB physics here, which might be useful to people trying to understand the polarization stuff:9. Comment #429744 by bamafreethinker on November 5, 2009 at 6:41 pm

Funnily enough, j. mills, a colleague of mine was explaining to me only recently that she reconciled her religious faith and her physics doctorate by thinking of dark matter as God.12. Comment #429764 by Jos Gibbons on November 5, 2009 at 7:46 pm
