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

At a BB singularity, there are no “particles”. The energy density is too high for even subatomic particles to form. Remember, mass and energy are the same thing ( E = mC^2 ), so it’s really massenergy that’s too high for matter to exist. If you have energy, which doesn’t take up space, you can have an infinite amount in a region of zero volume.
