is the singularities density REALLY infinite?

Nah, spacetime is a flexible medium so it's simply a self-compressing structure that's in free fall but it freezes the time it exists in before it can reach a zero volume.

thanks for the based physics related response, tired of the mathtards

that was total gibberish though. don't tell me you actually understood anything better based on that statement

since we don't have a quantum theory of gravity we don't even know if there even is a singularity.

Nobody know what it looks like in a black hole, and we'll likely never find out.

what' s the meaning of ''freezing'' here?

I dont know any GR, im currently struggling to study differential geometry since its useful for GR and QFT. Im pushing 40 but its too soon to have an opinion on singularities. Also, Fuck Katie Bouman's hole

time dilation at speed c is infinite, light doesn't experience time.
inside a black hole, the light cone (which contains all world lines passing through a point that don't exceed the speed of light) gets all squashed up (as in pic related) and eventually becomes so degenerate that all valid world lines are at the edges of the cone (with speed c). you'd expect the time dilation experienced by an observer following said worldlines to be infinite, hence time 'freezing'.
not sure if that's what they're referring to, or if I misunderstand this so take that with a pinch of salt
perhaps they're just referring to the fact that inside a black hole time and the radial coordinate swap roles, so that the center of the black hole is sort of a point in time and time becomes space
freaky shit, but the event horizon prevents us from ever peering inside a black hole to see what that might actually mean
