That then begs the question, could you destroy a black hole? If we had the ability to alter the fabric of spacetime, could we shrink that fabric so that the black hole either imploded or exploded?

I thought that the question was, why didn't the universe collapse into one black hole right at the beginning? With the argument I tried to outline, there was no black hole. The reason is, in short, the situation was not like where black holes are formed since then. The big difference is that, (1), now, the matter-energy for a black hole is in some region of space in our universe where that region is surrounded by the rest of the universe, and (2), then, the matter-energy filled the entire universe that there was, even if it was only the size of a baseball. Then, that matter-energy filled the whole thing. For that whole thing to have created some small black holes, the thing would have had to have partitioned into separate chunks. But apparently what happened is that the space expanded explosively, really before anything could collapse. Or, maybe the expansion was so fast that quarks, as close together as in protons now, soon were being separated faster than the speed of light and, thus, had no choice but to generate more quarks and, thus, more matter. We're talking really explosively rapid expansion. Or maybe the gravitational field of some matter-energy wanted to propagate at the speed of light, reach out, and connect with more matter-energy, but before that gravitational field had moved even 1 mm, space had expanded so much that the other matter-energy to be reached had already move to a few light years away. We're talking explosive, so fast that speed of light is so slow as to be nearly standing still and irrelevant. At least that is my intuitive understanding.
