I wish they would've talked more about how that can be. I've always understood black holes to have so much gravitational mass that they crush things down on a molecular level. If that's the case then how can we be inside a black hole?
I don't understand this stuff either, but the vague impression I have is that the theory is, instead of collapsing into a gravitational singularity, the matter rebounds which forms one side of an Einstein-Rosen bridge, which becomes a new universe. And we'd be in that universe.
