Doesn’t a black hole stretch time in a really weird manner? That would mean that no sensible answer can be given to the question. It could easily be that it takes either one billionth of a second or a trillion years, depending on where you are standing when observing the occurrence.
As I understand it, the enormous gravitational force causes time and space to become inverted. Instead of velocity being defined as time to displace position, time occurs over displacement. A person on the event horizon would be apparently frozen in place until they eventually faded to nothing. Not sure how that analogy works since light doesn’t escape a black hole but it’s how Brian Cox explained it.
Seems that way. Physics predicts completely wild outcomes at the extrema, in this case gravity but also for things that are very small. Quantum entanglement is a very curious phenomenon seemingly transferring information over vast distances instantaneously, faster than the speed of light which is impossible.

Does that still mean that the concept of “time” is not defined in a useful (human-understandable) manner in a black hole?
