The Early Universe Could Have Been Full of Very Dark Holes
WEB1 day ago · One such mechanism is a "direct collapse", in which early structures of the unknown, invisible substance known as dark matter confined gas clouds, while background radiation prevented them from forming stars. Instead, they collapsed into black holes. The trouble is that only a minority of dark matter halos grow large enough to form such seeds.
