One possibility is that space-time has been filled with matter of the kind that wakes up our universe. One can visualise a random soup; but in such a soup, gravitational forces would cause matter to aggregate and then coalesce as in black holes. Further aggregation could result in gravitational collapse, leaving a zone with very little matter remaining free within its sphere of influence. If the enormous energy were then to be released in a Big Bang, a universe would be created.
If infinite space-time is filled with matter which is in a ferment of gravitational motion, it would be nice to postulate universes of matter and anti-matter in roughly equal numbers in collapsing and expanding modes. We may be seeing the first signs of such things in the Hubble observations of outer space.
