Is it infinite density at its center, and if so, why doesn't GR breakdown at this point? AG It almost certainly does. Unless spacetime is truly a continuum, hence infinitely divisible, there must come a point where it turns into something else - or always is something else, if you prefer - a quantum foam, or whatever. I was trying to make a specific point; namely, if a singularity is physically impossible, the question of the existence of a singularity in the interior of a BH is solved. It doesn't exist!
