And the event horizon isn't so serious. There isn't such a stark demarcation between events inside and outside, where I can't know what happened inside or outside. I don't think that's the resolution either, but it was worth a try.

This is probably it, though.

I can say that this is not a situation where we can follow the chalk. We can't start at the end. So it's still a conjecture. I think it's very profound, though. I kind of imagine Juan Maldacena, who's part of this, with Lenny Suskin, they were kind of like, oh, it's like ER equals EPR. They couldn't even formulate it properly. It was like an intuition that they had kind of

landed on and now are trying to formalize. But to take a step back, one way of thinking about ER equals EPR, you have to talk about holography first. And holography, both Juan Maldacena really formalized it, Lenny Susskind suggested it.

The idea of a black hole hologram is that all of the information in the black hole, whatever it is, whatever entropy as a measure of information, whatever the entropy of the black hole is, which is telling you how much information is hidden in there, how much information you don't have direct access to in some sense, is completely encoded in the area of the black hole.

Meaning, as the area grows, the entropy grows. It does not grow as the volume. This actually turns out to be really, really important. If I tried to pack a lot of information into a volume, more information than I could pack, let's say, on the surface of a black hole, I would simply make a black hole. And I would find out, oh, I can't have more information than I can fit on the surface.

So Lenny coined this a hologram. People who take it very seriously say, well, again, maybe the interior of the black hole just doesn't exist. It's a holographic projection of this two-dimensional surface. In fact, maybe I should take it all the way and say, so are we. The whole universe is a holographic projection of a lower dimensional surface.
