Black hole formation without star collapse is pretty amazing. I wonder if this is something that could only happening in the early universe, when everything was closer together.
- digging 3y agoYes. These primordial SMBHs can have masses comparable to entire galaxies. You most likely won't find that much matter collected densely enough anywhere in the modern universe, or ever again.
- amatecha 3y ago"ever again".. until the universe collapses in upon itself? (Is that still a plausible theory as to the fate of the universe?)
- lazide 3y agoCurrent theory is it expands forever until nothing has a chance of ever interacting with anything else.
- SoftTalker 3y agoIf you believe Roger Penrose, at that point spacetime ceases to exist since all matter has thinned out to nothing, all black holes have evaporated. Then, because of math I don't understand, a conformal rescaling happens and you get a new Big Bang.
