So if it becomes a BH, it seems highly unlikely it started out infinite in spatial extent, which is what you and Brent conjectured. *It doesn't become a black hole of the universe is infinite. Equations for the formation of a black hole assume that there is no significant amount of matter outside the event horizon. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* You agreed that since the universe has a finite age, if it's infinite in spatial extent, that would necessarily have occurred at its origin. But although Penrose's theorem suggests it started as a BH, we can be relieved of that illusion based on our extensive knowledge of the interior and behavior of BH's.
