Why no 'Big Crunch' a femtosecond after "Big Bang"?
When the Universe was the size of a grapefruit, with the mass of 100 billion galaxies (actually, 20 times that mass, I suppose, given dark matter and dark energy), why did it not instantly suffer gravitational collapse into a megamega black hole?
After all, nothing (except Hawking radiation?) escapes from a puny black hole with the mass of only 100 million Suns or so.
