I understand the theoretical concept of multiple universes. That there are so many, almost an infinite number, that it is possible that somewhere out there, theoretically there could be another earth and even another me; out there somewhere. However: The Ace Rimmer concept, where each decision I make; the opposite is played out, on an other planet; is just silly, or over the top. Simply because, it would mean that other mes, would be popping into existence, each time I make a choice and then other mes would be popping up, each and evey time, each me, made a choice. What I will accept, was another me, was born somewhere else, in another universe and it lead its life; as it came. Which could have been very different to mine. The numbers could support such a thing happening.If MWI is correct, then any event will cause a split of the Universe, meaning that considering the amount of events, the linear part of the branch, will be "infinitely" small compared to the time it takes the brain to make a choice. The weird thing is that you continue in two separate minds after each split, but right now in this moment, you only perceive one. That could mean that the "meaning of life" could turn out to be a matter of always keeping on track with the version of you, that makes the right choices. Then it all becomes rather close to what we experience with our consciousness and our feeling of being able to choose. Highly speculative I know, but whereas causal determinism closed the door on free will, MWI opens it slightly, even if it's yet only a hypothesis. Anything concerning free will is also just a hypothesis at this particular moment of branching.
