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

Math.

Density = Mass / Volume

As the volumes reduces down to effectively zero (one Planck Volume, approx. 4.2E-105 cubic meters), any massive object’s density approaches infinity.

This makes a black hole, which by definition has collapsed down past that lower limit on volume, literally a Divide By Zero Error.

PS – Think of Planck Volume as Absolute Zero for size.
