I was thinking today about black holes. I was imagining how they formed a singularity, not mathematically, but physically and I got stuck at the Planck density. It's not a singularity yet and even with the entire weight of the rest of the object on top of it, you shouldn't be able to pack more energy. So I imagined it pushing back, which would then cause a shockwave through the material still falling in on it, creating a moving wave at the Planck density. Which would overwhelm even gravity and blow off a large chunk of the black hole. Anything it ejected would have already passed the event horizon so I imagine a black hole as a constantly exploding and collapsing cycle. I then tried to figure out what would happen around the black hole. The amount of gravity required to get energy density to the Planck scale is huge, so space-time would be dilated to an extreme, and as the black hole collapses, the dilation would get more and more extreme, then as it exploded, it would lessen slightly. So I would bet on some sort of gravity wave. I thought about if anything like that had been detected emanating from a black hole and hit a snag. The extreme time dilation would mean that even if the milky way's black hole explodes in a microsecond of it's own time, it could take billions of years from our perspective. Any thoughts / glaring errors?
