So as the black hole nears the end of this cycle of evaporating away, it takes a very long time, much longer than the age of the universe, it will be as though the curtain, the event horizon, is yanked up. Like it'll literally explode away. Just boom. And the event horizon, in principle, would be yanked up. Everything's gone.

All that information that went into the black hole, all that sacred quantum stuff, gone, poof, okay, because it's not in the radiation, because the radiation has no information. And so it was an incredibly productive debate because in it are the signs of what will make gravity and quantum mechanics play nice together, you know, some quantum theory of gravity.

Whatever these clues are, and they're hard to assemble, If you want a quantum gravity theory, it has to correctly predict the temperature of a black hole, the entropy of a black hole. It has to have all of these correct features. The black hole is the place on which we can test quantum gravity.

I'm unhappy with that. I would not be happy with information loss. I love that it's telling us that there's this crisis, because I do think it's giving us the clues. And we have to take them seriously.

We have to come to the rescue. As Lenny Susskind in his book, Black Hole Wars, his subtitle is, My Battle with Stephen Hawking to Make the World Safe for Quantum Mechanics. Yeah.

In some sense, it says there's no interior to the black hole, nothing ever crosses. So I gave you this very nice story that there's no drama. Sometimes that's how it's described at the event horizon and you fall through and there's nothing there. This other idea says, well, hold on a second.
