"[1] Big Bang... particle-antiparticle creation briefly got out of hand, more pairs being created than were reabsorbed back into radiation. ...[T]he present Universe is much larger than a sphere of light rays which started out from the Big Bang... Sometime in the past, the Universe... expanded faster than light... Most of the Universe we have not yet seen, despite traveling at [c]... not yet having had time to reach us. ...In the first fraction of a second... the Universe must have 'inflated' faster than the speed of light and particle-antiparticle pairs were produced faster than they could be reabsorbed."
