Abstract:
We discuss recent astronomical data showing that the role of massive primordial black holes in the Universe is much more significant than previously thought, both for the present Universe and for redshifts of the order of 10. We consider the model proposed in 1993 accounting for the primordial creation of heavy and superheavy black holes with a log-normal mass spectrum, which naturally explains some facts about the Universe that are unaccounted for in standard cosmology and astrophysics.
Keywords:black holes, massive and supermassive black holes, gravitational waves, globular clusters, formation of galaxies, the Universe at redshifts of about 10.
