So you just got to be careful about all of these things.

So I think that the details matter here.

You know, there's a way that we have a thinking about black holes that is sort of idealized.

Like I wrote a textbook.

on general relativity and you can learn about black holes in there, but the real world black holes are messy and they're made of stuff and things like that.

So I don't actually think it's true that you see an enormous amount of the past of the universe in a real black hole.

In a real black hole, you would, as you know, get spaghettified and die very quickly, right?

So if you're in a real evaporating black hole, you would first get spaghettified

and then you would be released as a stream of black body radiation.

And none of you is experiencing anything here.

So I think that you don't need to worry.

You would see more maybe than you would if you were outside the black hole, but there's no apparent paradox that you're going to see the whole thing.

I think you should always think about, I mean, what I would like is that everyone in the world thought about space-time diagrams.

And light cones, you know, your past light cone, which is the set of all things that can send light signals to you without moving faster than the speed of light, it never covers the whole universe.

It never sees the future.

It never sees things that are further away from you than the speed of light can get.

That's true whether you're inside a black hole or not.

So there's some quantitative question about how much you see, but there's no worry you're seeing things that didn't happen yet before the black hole evaporated.

You're the one falling into a black hole.

There's other bummers you have to worry about.
