what does the definition of a black hole’s singularity mean when they say zero volume, infinite density?

Question

formulaically, i understand the math. My question is more on the theoretical behaviour of something like a singularity.

How can something have zero volume but infinite density? How can something that don’t exist be infinitely dense?

Also, are all singularities the same and behave the same and have the same properties, regardless of the mass of the black hole?

For eg. A blackhole with 100 million solar mass vs another with 10 million solar mass. You take both mass, divide them by zero, and you get the same answer- infinite density.

Sorry for the juvenile question, maybe i shoulda posted this in nostupidquestions instead.

Answer 1

It’s undecided if they actually exist.

A good rule of thumb, is that any time the word singularity is used, regardless of context, it means out models aren’t sophisticated enough to understand.
