• Question: When something goes through a black hole, if we speed up time will the particles eventually come out and we can re-create the object?

      Hmm. Interesting question. The answer is probably no. Black holes have such strong gravity that nothing can escape, not even light! So they are effectively trapped there. If we fast forward time they will still be trapped there.

      If you believe Stephen Hawking however he has come up with an idea that black holes can ‘evaporate’ but what happens when a black hole evaporates is unknown. As energy can only be transformed not created or destroyed I would imagine the energy would still be around but not the particles. And you certainly couldn’t put it back together again.
