  1. We are told a black hole collapses to a singularity. Nobody asks why it needs to go that far. I believe the object simply has to be massive enough to prevent light escaping. The lump at its centre will be there. You just can’t ever escape its gravity. If you can actually get that fat during the life of the universe. Time stops at the speed of light. Gravity at the event horizon stops light so presumably it stops time as well.
