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

Singularities haven’t been accepted as possible for about 40 years.

It’s now “believed” that where the maths predicts a singularity it’s the maths which is wrong/doesn’t account for actual reality.

A simple thought experiment to disprove a singularity is as follows.

If you take a singularity and double it in size how big is it?

It’s still a singularity.

So how many times would you have to double the size of a singularity to get the present size of the universe?

Infinite.

Can’t happen.

So basically any time a scientist mentions a singularity what they mean is that the incorrect theories/maths predict a singularity (and “unfortunately” these are currently our best theories) but in reality it would have some non zero size.
