Black hole information mystery.

[TheExplorer]

It used to be thought that once something went into a black whole, it was lost forever, but then Steven Hawking said that information could leak out. Then he renounced his theory because it did not agree with quantum mechanics, however apparently there is a new theory. Here is an excerpt from space.com about it,

 

The newly proposed scheme, in a nutshell, says space-time is bigger than was thought, and so there's room for the information to reappear.

"Information only appears to be lost because we have been looking at a restricted part of the true quantum-mechanical space-time," said Penn State's Abhay Ashtekar, who has come up with the idea. "Once you consider quantum gravity, then space-time becomes much larger and there is room for information to reappear in the distant future on the other side of what was first thought to be the end of space-time."

Does this mean, if I jumped into a black whole, I wouldn't be gone forever?

and also what about the big crunch? if the whole universe collapses into a black whole? would it come back?

It has something to do with quantum entanglement and for even complex idea, it involes Ads/CFT corespondence, which talks about DeSitter Space. Ads is short for Anti Desitter Space while CFT is short for Conformal Field Theory. Here is the article from arxiv.org, written by Stephen Hawking, himself. I acknowledge Mr. Mordred for his kind sharing of this article

I have answered this question long ago in this post

Hope you enjoy astronomy.

 

Good luck
