> Imagine approaching a black hole and being spaghettified a light year across where you have to endure a thousand years of physical torture before being destroyed at the event horizon?!

This would only happen for very small blackholes, and even then from your point of view time would act normally.

Is there any evidence for time dilation though? My 1000 years number is a rough guess, and it could be shorter or even longer than that. I was thinking since physics breaks down that you would have to endure being spaghettified whilst still being able to feel and have nerves intact and thinking capacity.
Relativity means time slows down for an observer, not for the observed. You would see the universe around you rapidly speed up and eventually die.

Yes, but it's irrelevant.

For an outside observer it might seem like a long time, but not for you.

Even if your brain is perceiving time normally, even if you’re not experiencing enough acceleration to be crushed yet, I really don’t want to think about the effects of a severe time-dilation gradient on the rest of the body.
You would have been cooked by x-rays before that happened.
