#468 – Janna Levin: Black Holes, Wormholes, Aliens, Paradoxes & Extra Dimensions

I think they thought they were solving theoretical, mathematical problems, but not describing what turned out to be the end state of gravitational collapse.

It does both. So it also describes the sun from far away. So the same solution does a great job helping us understand the Earth's orbit around the sun. It's incredible. It does a great job. It's almost overkill. You don't really need to be that precise as relativity. And yes, it predicts phenomenon of black holes, but it doesn't really explain how nature would form them.

But then it also, on top of that, does signal the breakdown of the theory. I mean, you're quite right about that. It actually says, oh man, but you go all the way towards the center and yeah, this doesn't sound right anymore. Sometimes I liken it to, you know, it's like a dying man marking in the dirt that something's gone wrong here.

It's signaling that there's some culprit, there's something wrong in the theory. And even Roger Penrose, who did this general work trying to understand the formation of black holes from gravitational collapse, He thought, oh yeah, there's a singularity that's inevitable. There's no way around it once you form a black hole.

But he said this is probably just a shortcoming of the fact that we've forgotten to include quantum mechanics and that when we do, we'll understand this differently.

I think everybody would say that. I think everybody would say the closer you get to the singularity, for sure you have to include quantum mechanics. You just can't consistently talk about magnifying such small scales, having such enormous ruptures and curvatures and energy scales and not include quantum mechanics. That's just inconsistent with the world as we understand it.
