Good answer. But, if you really want to know how much space a black whole takes up ask Laz. He’d know.

Based on the No Hair Theorem a black hole has only three properties: mass, electrical charge and angular momentum. Diameter I assume is a function of the mass.
Based on Hawking Radiation all black holes are losing mass over time although the process is very slow. An ping pong sized black would take 1.815951e+58 seconds to evaporate.
Our perspective in space-time is not the same as the perspective beyond the event horizon anyway.
Do black holes actually exist or do cosmologists believe they exist? And because cosmologists believe they exist, they believe they see them. I think the existence of black holes is less likely than the existence of sasquatch/big foot.
A singularity is a mathematical concept. Many things can be treated mathematically that are impossible in a physical world. It may be just fine to treat the 'gravitational well' as a singularity for mathematical calculations, but physically, an 'infinitely dense' material occupying zero space makes no sense.
This article is the first I have ever seen that actually estimates the real size of black holes. Most others treat them as "infinitely small". Whether something that's millions of light years away is the size of a golf ball, or or the size of the earth, or even infinitely small, is irrelevant for mathematical analysis. That doesn't make it zero size, though.
Is the 'gravitational well' a physical 'singularity'? I think not.
It is. Our impression of “solid” is the result of the Pauli exclusion principle, that no two electrons can share the same state. But atoms are mostly empty space, mostly “nothing.” It takes tremendous force, and gravity does that, to cause the space inside an atom to be compressed.
Another thing is that on paper, that ping-pong ball or 2 mile sun-mass black hole is the event horizon, and not the size of the mass. If you get that close, you can never leave.
Did Adam & Eve have belly buttons?
If in a vehicle traveling at the speed of light, and turned the lights on would would it make a difference?
If you could run at the speed of sound, and screamed, could you hear it?
What is the speed of dark?
Have a great day!

The first or one of the early Hidden in Plain Sight books postulates that gravity is not exactly the equation we use now, the equation that results in a “singularity.”
It postulates that at extreme levels, gravity “balances,” pushes back on itself, and that the mass of a black hole is not concentrated at a point, but is (for want of a better visual image) a hollow sphere at the event horizon.
Reading this really blows your hair back. We are so tiny and inconsequential in the scheme of the universe.
It makes me believe that the power of God is beyond our comprehension.
There is also the possibility that the collapse does cause the mass to be compressed to zero size. There may be another type of degeneracy (something like the Pauli exclusion principle) that prevents the matter from being compressed to zero size.
Oops!
There is also the possibility that the collapse does not cause the mass to be compressed to zero size.
Are Black Holes what forms Galxies due to gravitational pull?
