Hi, sorry - forgive me for posting (I am not much of a science guy but I am still interested). I am just watching a documentary (I know not a great source for scientific information - but it got me thinking). In the documentary it talks about the many worlds theory (which I believe is different from the multiverse theory? It would seem that other copies of Earth makes more sense in multiverse theory as opposed to many worlds?) In the documentary it says that (with many worlds theory) in every decision we make we split the universe. I.e. If I choose a to order a latte over a mocco, then the universe will split into two parallel universes. I know this theory isn't fully accepted but the problem I see with it is that if everything is identical in the universes before hand (down to the smallest particles in our bodies) - then wouldn't the exact same decision be made every single time? - i.e. we have no free will - only fate due to the way certain atoms behave in our bodies? Meaning there could be no split and therefore no creation of a parallel universe? - I don't know much about science tho - just interested in others thoughts :). Or is it something to do with a particle being able to be in two places at the same time?
