For the geeks among us: there was some really exciting news in Nature this morning. Astronomers have located the missing ~30-40% of the baryonic (normal) matter in the universe. It's especially cool because it matched predictions.
Here is the article: http://www.nature.com/cgi-taf/DynaPage.taf?file=/nature/journal/v433/n7025/full/433465a_fs.html And the paper: http://www.nature.com/cgi-taf/DynaPage.taf?file=/nature/journal/v433/n7025/full/nature03245_fs.html
This significantly increases the probability that the standard cosmological model is correct.
The next thing to look for is 'sinks' of dark matter at the ends of these baryonic filaments pulling them apart. The picture is starting to look as though the universe is covered in dark matter points with baryonic filaments interconnecting them like a web and galaxies interspersed in the empty space between.
