  Black/white holes role in cosmology

+ 0 like - 2 dislike
117 views

Black holes appear to be an end-stage of a matter, and they combine "silently" (unlike the colliding stars or galaxies). So, after enough while, there going to be a single black hole in an empty space (except a massless radiation, which won't interact anymore).

And also, the durable collapse gets nearly concentrated into the proper time of a falling observer.

Then, if we consider that simply, a time inside a black hole seems limited; however, if a falling matter somehow proceeds (there - inside) to flying away (like bouncing back or something), the event horizon disappears for it like that of an accelerating observer when acceleration isn't not continued, providing geodesic completeness. 

What are the effects of an angular momentum? Why would there be an Inflation? What about a radiated energy (inside and outside, separately)?

I've found that it seems called "cycling Penrose's universe", so lots of sources are easily searchable, yet I'd like to save the question for improving (as aside: quite fun, considering this also mine question https://physicsoverflow.org/44702/role-of-quantum-effects-in-brain)
