how can a singularity have infinite density?

Question

For one, wouldn’t that mean they have a volume of zero? how does that work?

Answer 1

ELI5: Mathematically, that’s exactly what it is. A certain mass occupying zero volume, which means infinite density *by definition*.

Gravity still works because mass is still mass. Entire galaxies are still bound by and orbit around similar singularities (“supermassive compact objects”) in their centers.
