In black holes, which are still only theoretical, there is a singularity, which is also theoretical.

Well at least you're thinking 3 dimensionally - get fed up of people asking what's on the other side as if it were a magic disc.
Lots of people will tell you a singularity, or a quantum singularity (which sounds cooler) but the truth is we don't really know. You'll have heard some people say the laws of physics breaks down inside a black hole - wow, cool stuff - except thats backwards, all that breaks down is our ability to explain whats happening.
Though black holes are taken as a given they rely on General relativity (Einstein's masterpiece) though if there IS a point of infinite density at the centre, this object - being tiny - would have to be described by quantum mechanics - the physics of the very small and the other great theory of the 20th century. Problem is, the two theories don't work together. When you try and use them both the equations go haywire.
Other possible explanations of what a black hole might be are black branes or gravastars. Its fascinating stuff. Good luck in your research!
Kind regards, etc

All this use of the term like singularity and talk of event horisons are fun but what it boils down to is a black hole is a star.
.
Forget the word hole. It's misleading. It is black, but a better way of discribing it is dark. It's a round ball. It's a star that doesn't shine. As it sucks in matter it enlarges.
.
Many people imagine a black hole is like a drain or something and that if you could go through it you'd end up somewhere else. Those imaginative ideas have come from science fiction.

yes by definition a quantum singularity is at the center of a black hole, a singularity is a point that has infinite density and zero radius.. the black hole is simply the region around the singularity from which light cannot escape.

If the BB is not rotating, then yes, there is something at the center. But once you get down to about 10^-35 meters or so, the concepts of "place" and "time" get sort of fuzzy.

yes a mass compressed to a great density like billons of ton per cubic centimeter

its called "the singularity"
