Does a singularity at the center of a black hole have volume? If not, would the density be infinate?

In classical General Relativity, the singularity in the center of a black hole is a point with no volume and finite mass. It is also in the infinite far future, from the point of view of anyone outside the hole. At any finte time, the matter forming the black hole is still falling towards the singularity, and is not yet in it. So the singularity doesn't really exisit in our Universe---it is shielded by the event horizon of the black hole.
Quantum mechanics probably makes the singularity impossible, in away that we don't fully understand

its an interesting question. The singularity mathematically has zero volume to an observer on the outside, however inside the event horizon space and time act very strangely and the concept of volume doesn't apply anymore. Its a case of observer on the inside or outside and different results for both

Singularity has volume, this is before the Big Bang. A black hole is not a hole, it's a massive body bigger and stronger than the sun, it's so powerful that it eats light.

A singularity does not exist. Also not in the center of a black hole.
A infinate density is not possible, then there shoud also be infinite matter in that place.
If there was infinite matter (somewhere), then our universe would have collapsed into that point.

Mathematically it has zero volume, infinite density.
Of course nobody really knows, and our scientific theories are not complete enough to really explain the nature of a singularity.

Hi. Hard to say. Weird things start happening near the surrounding event horizon. For most intents and purposes the event horizon determines the volume.

Well ,mathematically speaking it's mass approaches infinity and its volume inversely approaches zero but you can never reach absolute zero or infinity so yes it has some volume just not very much.
