But we're all basically just playing with...

some frameworks, like mathematical frameworks, that give us intuition for what we might guess, and then we're not precise enough with what we're assuming when we compute something, and then, oh, this don't fit together.

Like, that's the vibe.

But I think I wouldn't try to scare, like, a random person with it.

I would just point out that somehow the bread and butter of, like, a physical theory where you don't make a measurement is seeing that, like, these assumptions don't tie together, so something has to be wrong, then propagating it back and trying to fix it.

So, I mean, I think some of it sounds like there's literally just a sense in which, like, I have so much matter in some region that now even light can't escape.

And the way that I see it is, like, from a Penrose diagram there straight up is just some region that I cannot access from infinity.

So it's very much, like, a feature of the geometry.

But then there's other fun things about, like, the fact that if you put enough energy in some region that you're going to end up creating a black hole.

And that often is tied into this question of, like, quantum gravity has to be weird and different, you know?

And so...

And it's neat, though, because you see how much people, when they see, even though it's not actually the horizon, when they see these images of a black hole and the accretion disk around it or whatever, generating the light.

Engineering is cool, the fact that they can reproduce that image or stare at a black hole.

But it literally is a black hole in the picture, which is kind of funny, right?

The way the light is bending around it.

But I think that the fun thing is really just more like...

like the way a physicist would at first in her counter is like, there's a very specific solution to Einstein's equations.

So there's a differential equation with a specific solution that then has some weird ass properties of like the causal structure of like where like particles are going to end up.

So.

So that's the type of question.
