IMHO, that was a very long-winded non-explanation. Basically the "answer" comes down to this: 1. We really don't know. We don't understand the rules of physics

IMHO, that was a very long-winded non-explanation. Basically the "answer" comes down to this: 1. We really don't know. We don't understand the rules of physics well enough to model the behaviour of stuff in such "extreme" situations. 2. If you still insist on asking that question, I could give you a plausible explanation of why the question is not really the right thing to ask: "small" black holes tend to evaporate very quickly through the process of Hawking radiation -- in effect producing photons, matter, and every possible kind of "stuff". So even if there was something akin to a black hole, early in the universe, (and if we could apply our rudimentary understanding of gravity and quantum mechanics to even talk about black holes and Hawking radiation) it wouldn't trap the stuff for long... in fact it would be spewing out stuff in copious amounts, and very quickly at that.
