It seems amazing to calculate the odds of this vacuum arising from the ashes of some proverbial ''nothingness''. Since the wave function governs every possible chance of any reality arising, it must mean that it ruled the very initial standards during the first instants of big bang. Essentially quantum mechanics states that every period in which the universe exists, exists alone for the wave function of possibilities; this means that when big bang occurred, the state which we observe today was in fact chosen from an infinite amount of other possible realities.

This means that for this specific reality (*that is* this specific space and time concerning matter and energy) was chosen from another possible infinite amount of realities.

With resorting to parallel universes, the chance of our universe appearing was inevitable. If you have every situation arise (as you would expect in an infinite amount of universes) then you would also not expect any reality to no manifest itself. So multiple universe theory can serve to satisfy an answer to why reality seems as though it is...

... But equally, i have expressed my displeasure for multiple universe theories... I personally do not attend to the idea that there are other definitions of the whole, we call ''universe'', outside the known laws of QM. As far as multiple universes are concerned, is that our universe we observe everyday is not very important, since every universe-possibility that is probable, already exists, somewhere 'out there.'

The definition of universe should mean ''everything'' - *or* ''everything which exists.''

So if any one here likes parallel universes, could they explain to me how it would make quantum mechanics more barable?
