IANAP, but the way I heard it explained is that a black hole bends space-time so much that a straight line curves back into itself as a circle. Thus light fails to escape not because it lacks enough speed, but because there is no straight line it can follow that exits the black hole.

Yeah, inside the event horizon, no matter which direction you look, you are looking at the singularity (whatever that looks like, which no one knows). That has always tripped me out.

Imagine you’re standing on a globe and on the other side there’s a point (the singularity). Every direction you walk is towards the singularity. It’s kinda like that but with another dimension
