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.
Is a singularity very dense matter? Yes.
Infinite? I don't think so.
The singularity is an assumption, not a scientific fact. The Big Bang theory is to do with the expansion rather than the beginning of the existence of this universe.
