"Little Pop" Universes?

[Bad Penny]

I've been reviewing the work of Professor Laura Mersini-Houghton, and it dawned on me that nothing in her work precludes the possibility (the reality of which I strongly suspect) of failed or failing or otherwise non-thriving universes that began at too low an energy state to result in a universe of our scale and energy state, in other words, universes that began, not with a Big Bang, but with a Little Pop.
