Cosmological inflation. That would be... number 98 on my list. The astrophysicist Jean-Luc Lehners wrote a paper called 'Eternal Inflation With Non-Inflationary Pocket Universes' that discusses the theory in some detail.

[and here he starts to quote]

'If eternal inflation occurs, it generates pocket universes with all possible vacua. Moreover, since each type of universe is itself produced an infinite number of times, all possible histories within these pocket universes are physically realized. This implies that we should not restrict ourselves to considering only pocket universes in which slow-roll inflation occurs, but in fact all physically allowed cosmological models will be realized an infinite number of times.'
