You ask if something can exist "something concrete (not abstract)". -edit- that is infinite.
The theory of a Black-hole is just that. Is there an end to how dense a singularity can get? No. Theoretically it can continue to be more and more dense. At infinitude. There is nothing more "concrete" then matter its self. A black-hole is that mater condensed and can theoretically continue to condense more and more.
If you mean something that is proven beyond theory, then the idea of numbers. One can always count higher. There is no end to numbers. Count and count and count on. You'll always have another number to go to.
Ina black hole, you are talking about a property of being infinitely dense. That is not the same thing as having an infinite number of anything in real life.
Being able to count infinitely is a potential infinite. You can never actually arrive at infinity. The question the thread is concerned about is whether an actual infinite can exist (something real that has an infinite number of things).
Density is defined as "number of things per unit volume", so infinite density is equivalent to infinite number of things.
That is, if a black hole indeed has infinite density...
