Based on what we know, if a human were to survive past the event horizon, would they see the universe fast-forward all the way to heat death? Would it move backwards? Or would spacetime break down in such a way that it’s impossible to know?

[This video](https://vimeo.com/8818891) shows an simulation of what it would look like to fall into a regular black hole. [This website by the creator](https://jila.colorado.edu/~ajsh/insidebh/schw.html) explains all the relevant physics.
It is a common misconception that you can see the entire future of the universe when falling in a black hole. This is not true. Also, the other comment here stating the outside universe would become infinitely bright is not necessarily correct. This is only the case for an observer *hovering* right outside the event horizon. An observer who falls into the horizon won’t see this.
