The June 13, 2011, issue of New Scientist magazine summarized recent work by astronomer John Kormendy of the University of Texas at Austin and cosmologist Jim Peebles of Princeton University, as well as others. Astronomers are finding evidence that, according to Peebles, shows that "galaxies are complicated and we don't really understand how they form. It's really an embarrassment."
In the January 2011 issue of Nature, Peebles summarized two papers that described galaxy discs that totally failed to fit the standard theories of how galaxies supposedly formed. The galaxies they investigated had very dense points of mass in the center of their cores, presumably black holes. But only about half of them had a "bulge" of associated stars nearby. The other galaxies were razor-flat in side profile, even though they appeared brighter near their centers.Read the rest of 'Wildly Unexpected' Galaxies Defy Simple Naturalistic Explanations here.
