I'm by no means an expert on this subject, but I think the possibility of parallel universes could be explained as probabilities only. Maybe they exist for a fraction of a quantum moment until the probability becomes a fixed value.
Say for example an atom is split, an electron at this point may either zig or zag. For a quantum moment it is actually doing both, until one probability becomes actual, at which point the 'false' probability wave/reality collapses.
Whether this is on the right track or whether it is pure fantasy will have to remain speculation until someone can figure it out.
There is that famous quote which i'll try and paraphrase here: If you think you understand quantum mechanics then you do not understand it. (or if you are not confused by QM then you do not understand it... something like this).

A finite number of monkeys with a finite number of typewriters and a finite amount of time could eventually reproduce 4chan.
