things in excess of c may experience time reversal inside a BH, how does this affect their existence. ?
Could a BH bring fundamental particles close enough together to destroy each other
Could Black Holes cause the reversal of the Hot Big Bang?
QuoteCould Black Holes cause the reversal of the Hot Big Bang? Some theoretical physicists have speculated that rather than forming a singularity, the center of a black hole is an Einstein-Rosen bridge to another universe. To an outside observer, this situation is indistinguishable from a black hole with a singularity at the center.See: https://en.wikipedia.org/wiki/Black_hole_cosmology
At the central singularity, any matter would destroy itself with antimatter, producing radiation. But all radiation would also end up at the singularity too. Effectively, to an outside observer, the mass/energy of the black hole would reflect all the matter, antimatter and radiation that ever fell into it.
Gravitational forces rip apart anything including molecules and fundamental particles shortly after crossing the event horizon
I understand normal matter can not pass through a singularity for some strange reason
Relativity suggests that all matter would be crushed by an unstoppable force into zero space at the center of a black hole: the singularity. According to this theory, no physical object like a spaceship, a mouse or a molecule could survive impact with the singularity. Of course, Einstein viewed the existence of infinities (singularities) as an indication that hs theory failed in these extreme cases, so I don't think Einstein himself would be surprised if some other physics took over in these extreme conditions.For example, relativity ignores quantum theory. In quantum theory, you can never simultaneously know the precise position and energy of the same particle (and several other uncertainties). So quantum theory hints that the singularity may not be exactly zero size. Perhaps some small things (eg electrons) might survive impact with the singularity in some way?There is another potential loophole (literally) in the theory of singularities. If the black hole has a lot of angular momentum, and the black hole collapses just right, it is theoretically possible that the singularity could be a donut, rather than a point. In theory, if you shot a small spacecraft through this loophole, the spacecraft might just make it through intact. But then the twisted spacetime becomes even odder...
