What happens inside a black hole is basically unknowable. We can only ponder the math which leads to ideas like space and time swapping roles once you cross the event horizon.[0] The only thing that comes out is hawking radiation, which is sort of like... half of nothing.

- codethief 1y ago> space and time swapping roles once you cross the event horizon This is a common misunderstanding. Space and time don't swap roles. It's just that there's one rather popular coordinate system (Schwarzschild coordinates) whose coordinates t, x outside the horizon correspond to temporal (timelike) and spatial (spacelike) directions, respectively, and inside they correspond to spacelike and timelike directions. What we mean by "timelike" and "spacelike", however, does not change.
- smolder 1y agoThat's what the video link (PBS SpaceTime) explains. Quite well, IMO.
