you can travel forward in time, not back. Photons don't age

No, I am travelling backwards from the perspective of an outside observer

If you are inside a black hole, it does not matter what happens to you because you are no longer part of the universe.

Events inside of a black hole have no bearing on the universe.

Black holes are part of the universe. In this thought experiment, I am in a black hole. QED

the bottom line is that time moves forward, besides spacetime, you can reverse physical events, though you would be repeating them, not going back in time. stupid thread, and Im stupid, I've been studying relativity

yes, stay in a safe orbit around them and time for 50 years and when you come back to Earth you'd be in "future"

explain, I know they don't but what would be different if they did?

Realise... That nothing in universe is "infinite".. Blackholes = not infinite mass but mass tending to infinity.

Hence they disintegrate at rate tending to infinity but not infinity.

No. The 'secret' to time travel is a Nokia 1011 and a microwave utilising 8.0-18.0ghz coaxial isolators.

>all information that falls in to a black hole is gone forever and can never be recovered
>black holes release matter through hawking radiation until they evaporate
Which one of these is true? If the black hole evaporates then everything that fell in would be released. Matter cannot be created or destroyed, so that matter does not simply disappear when the black hole evaporates. Thus, it is recoverable.

well someone here explained it. It all has to do with relativity and space-time, as you approach the speed of light, you stop aging, though the infinite process doesn't end, so you just age infinitely slow, to my understanding.

Energy can not be created or destroyed. Matter can be created as well as be destroyed.
