DA, a question re:
"We know for a fact we can pack all of the stuff into the universe into a theoretical point (or if you prefer string). We do that in the lab all the time with Bose Einstein condensate. And it is quite likely that this is precisely the nature of a singularity inside the event horizon of a black hole (we just don't know)."

The difference, surely, is that a Bose-Einstein condensate occupies the space of an atom, whereas, by definition, a singularity occupies zero space. Isn't that correct?
