Let's say you could survive going through an event horizon and you let yourself get pulled in by a black hole. How much does the rest of the galaxy age before you pass it? Can you still see light coming in from the outside once you pass through?

That's not how time works.

Yes.

Nothing strange happens when you cross the event horizon. It's just a sort of imaginary line in the sand where you can't ever escape. Like traveling down a river with a waterfall at the end - at some point the current becomes fast enough that you wouldn't be able to swim against it, so no matter how hard you fight you're going to topple off the end.

i think you can see the light but it will be shifted and curved.

Somewhat related issue

Let's say you leave Earth, travel 1 light-year and then travel that light-year again when returning to Earth, all this at speed of light. It would take you 2 years to make the entire trip.

But how much time would it pass to the people on Earth?
