Can Black Holes Really Allow Time Travel and Survival Beyond the Event Horizon?

[Ali Abbas]

When somebody crosses the horizon of a black hole, the person would have the privilege to travel backwards in time (as shown in the movie 'Interstellar'). What are the possiblities of such a person to even survive after getting in a black hole, and how does he even able to travel in the past. Time travel in the future can definitely be considered due to relativity. Relativity also shows how can time be reversed, but how does a black hole cause time to be reversed? Can somebody explain me please?

No, they wouldn't. Movies are not good references for actual science.

Relativity also shows how can time be reversed

It does? Please give a reference.

It doesn't.

Assuming that the radiation environment doesn't fry you, you can survive crossing the event horizon of a sufficiently massive black hole. It's the tidal gravity that rips you apart, and that gets weaker for a larger hole. However, after that, all paths lead to the singularity and you will be shredded at some point.
