Can somebody please explain to me the idea of zero mass and infinite density, my mind just is not comprehending it, it seems almost illogical to me. Please help my brain make sense of this. Non-mathemetical please as I am not part of the scientific community. If the answer is just a simple "the extreme environment of a singularity breaks down all logic and laws" then I guess I'll just have to remember what I always say when the universe stumps me. To begin to understand we must first understand that we will never understand.
