#428 – Sean Carroll: General Relativity, Quantum Mechanics, Black Holes & Aliens

2966.175 - 2985.078 Sean Carroll

Big crunch probably doesn't exist, but if it did, it would be a collapse to a singularity in the future. That's what the interiors of black holes are like. You can be fine in the interior, but things are becoming more and more crowded.
