Regarding singularities, I have been pondering this for years now but noone seems to adress it so I need to front the question. How come black holes must have a singularity, after all they differ in size... obviously things are not crushed into a infinitely small point... it's obviously crushed down to the smallest possible and it seems to be lesser than plank - again - the black holes (I rather call it a planet / star) do increase in mass. I wouldnt say they grow, unless we say a star grows as comets crash into it ok it grows. But definately it increases in size as it collects more mass from things falling into it. The M87 black hole is definately NOT a infinately small point... so what the heck is up with this constant talk of a infinately small point? Does not make sense to me at all! A huge ball of the maximum pressure does make sense - and hopefully like much other materials where there exists a point of critical mass - it can explode ... voila ... the big bang. Im guessing if the M87* black hole suddenly exploded for unknown reasons - god damn there would be alot of mass comming out from "nothing"... That is 6.5 billion solar masses of nothing ...
