Just watched the documentary 'Stephen Hawkings Grand Design: Did God Create The Universe'. S.H. stated that the big bang was similar to subatomic particles that appear, disappear and reappear somewhere else following the laws of quantum mechanics. If that were so, wouldn't it also be possible for another big bang to occur in the palm of my hand at any moment? My background is not physics by the way, I'm an interested electrical engineer (from Belgium -> explains faulty English).
