God+QM

i just read this book, the end of Mr. Y by Scarlett Thomas, and i came a cross an intriguing thought experiment/ theory. it goes something like this (as i understand it).

if you rewind the expansion of the universe all the way back to singularity, then you end up with a quantum mechanical system.

this means that the universe at this stage would have numerous possibilities, each with a numerical probability of it occurring. here's the rub.

either all of these possibilities played out, expanding into all of the multiverses (i would assume that say there were an million universes and the probability of 2 particular universes was 2/10 and 3/10 then those universes would occur 200 000 and 300 000 times respectively). my understanding of this is a bit sketchy, i would suggest there are probably an infinite number of universes possible from this point.

the alternative to this is that if the number of universes is only one then something needed to occur to collapse the wave function of the quantum mechanical situation, i.e. an observation by an outside existence. the nature of the outside observer is not really important, for example it could (technically) be the creator of all things- as is advertised by religions, but it could also be one of those (spoilers for MIB) alien things at the end of the film

I don't make out this is completely my own thinking, i just wanted to shout it out there.
