Science (New York, N.Y.), 2010According to the present astronomical picture of the universe, all the galaxies condensed out of a diffuse medium about 1010 years ago. This picture arises out of the general belief that we live in an expanding universe. Extrapolating backward in time, it is inferred that the galaxies were all compressed at a beginning epoch into some sort of hot ...

Some of these aspects are already well known, for example the X-ray emission of clusters of galaxies and of Type I Seyfert galaxies, but ...
