If it is dimensionless - it stops being physical object and becomes a concept. If it is infinitely small - it can not exist in real world because the word infinity describes undescribable.

No observation has ever been made. No black holes have ever been seen. It is said that by observing surroundings it has been deduced that they exist. That alone makes it pure theory, with absolutely no relation to real world which observationally is made of 3 known visible dimensions. Singularity is supposed to be dimensionless point of infinite density. If it is dimensionless - it stops being physical object and becomes a concept. If it is infinitely small - it can not exist in real world because the word infinity describes undescribable. The only way to take black holes for real is take them for granted and accept many presumptions as facts, hence making it a religion. One never has, doesn't, and never will observe or recreate black hole in lab or universe because the theory itself firstly has defending mechanism that states that it can not be seen - to dismiss non believer, secondly it deals with infinities which are not objects but concepts so it actually falls in to domains of philosophy and not physical science.
Anyone attempting to declare that 99% of everything is missing is lunatic on a Big Bang Scale. Given only that Maxwell's equations solve for the speed of light, gravity must impede gravity. That alone renders black holes impossible.
