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

450 views

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.

We don’t actually know what the matter in a black hole looks like. We say it’s infinite density in no volume because that’s one way to interpret the math behind all of this. But it’s an attempt to interpret a mathematical function that no longer follows the rules of math. That’s what a mathematical singularity means – the math no longer works. Which is another way of saying we have no idea.

More modern interpretations think that inside of the Schwarzschild radius (the boundaries of the black hole that grows as its mass grows) is actually something like a ring of matter. This is because we’ve discovered that black holes actually have other properties, like charge and spin.
