I'm not sure how you got the "without gravity" idea from that post.

Gravity is, as you say, one of the ways we experience the curvature of spacetime. Black holes represent an extreme form of the curvature of space time (it becomes infinite at the singularity; which is a good indication that the theory no longer works at that point). So the only reason black holes exist is because of gravity/spacetime-curvature.

My apologies, as I completely missed "gravitational" in the opening paragraph. Sometimes I read things too many times and make assumptions.

If gravity is the strong factor in black holes and gravity can affect space-time; then can I assume there could be a time distortion generated?

Does space-time curvature become infinite in all singularities or in a theoretical "perfect " black hole. If the gravitational power isn't absolute, then could some energy escape at potentially high speed?

Black holes are formed when gravitational inward force overcomes both the thermal pressure outward and the degeneracy pressure keeping electrons and neutrons from compressing. Two neutron stars could also combine to continue degeneracy and become a black hole. And of course, the maths show us that the extreme curvature of spacetime past the EH is enough to cause matter to instantly degenerate. 

Philosophy is better suited to "why" questions, but science observes that this process where stars sometimes lose their balance of inward and outward pressures is what distributes heavy elements around the galaxies. The universe thrives on equilibrium, it would seem, and matter appears capable of stability in two heavily compressed states as well as at normal densities.

Does this mean that matter is compressed inside a black hole without gravity? I was under the impression that immense gravity would be required; and that could produce a time distortion.

I thought that Einstein determined that massive objects cause a distortion in space-time, which is felt as gravity.

I think many people get the idea that the event horizon around a black hole is like an entrance, so they reason their must be an exit. The EH just marks the boundary where spacetime becomes overwhelmingly curved due to the mass of the former star core having overcome degeneration pressure to become so tiny and dense. Past the EH, there simply isn't a path in space or time that doesn't lead to the degenerate matter. Time isn't regressed, but the future of anything that crosses the EH becomes inevitable. 

I suppose my mind is trying to find a connection between 2 questions. Where does matter go when consumed by a black hole and where did all the energy of the big bang come from and why was it compressed.

Awesome! Thank you for your input.

Universe expansion

What I mean is that according to current theory, the universe is expanding and has been expanding since the big bang. I think that means the universe 14 billion years ago was concentrated at one point. I'm still struggling with whether that one point was surrounded by an empty universe or if the actual entire universe was just that one small point. Maybe that's another central question.

White Holes

Sorry, I think I should have said time reversal

event horizon of a black hole time “stops”

Are there any papers you can suggest regarding this hypothesis?  I understand that is subjective to the observer, but I'm curious to know what happens to the matter sucked into the singularity.

Since learning that the earth's core is years younger than its surface (due to gravity), I have begun thinking about how supermassive black holes may have an exit point that is chronologically as well as spatially distant from the singularity itself. If the expansion of the universe is related to time itself, than any regression in time goes back to a time period of a smaller universe. If you go back far enough (say 14 billion years), then the universe becomes a single point. It has been theorized that white holes may exist and those could be in the past as the massive gravity causes time regression for everything entering the singularity. So if a supermassive black hole produces a supermassive time effect, could that transport matter/energy back so far that the only exit point could be the Big Bang event?
Could this recycling of matter/energy also account for dark matter and quantum entanglement? I'm hoping someone can prove this wrong so I stop dwelling on it. Thanks!
