Or are you, like, less confused?

Like, who's really more confused?

So there's these paradoxes that come from, like, basically trying to say, okay, I think I know, like, it shouldn't be that ridiculous if it's a big black hole.

Like, the horizon isn't that special.

I only kind of know it, like, kind of...

like teleologically or like away from, like I don't know at the moment that I passed the horizon.

So then why can't I put some quantum fields on it?

And then like I have pair production, one of them will go out to infinity, the other one's gonna go inside.

And suddenly you run into these like issues of, uh-oh, like did I evaporate into a thermal system now?

Is it not unitary and all this fun hocking stuff.

So I think the thing that one should take away is that there are,

Still, I think situations where people don't understand all the assumptions they make, where they can just follow one step after the other, think that they're doing something that seems logical or not, and then they realize, oops, together something was wrong.

And so it's not breaking physics.

It's showing that there is something broken in our assumptions.

The physics always has to be right.

I think we believe that.

It's just we don't quite know, again, the regimes in which our assumptions are valid or which one is the wrong one.

So yes, there's a lot of active things.

I think I still have colleagues who believe that as soon as you cross a horizon, there's some firewall or fuzzballs.

There's different models for what happens behind it.
