Generally important macroscopic events are not the result of single quantum mechanical events but the average of multitudes of them. I suppose there is that world where you step out of bed and your foot falls through the floor, but in most of the worlds most of the particles in your feet are going to fail to tunnel past most of the molecules in the floor. If one or two makes it, that's a parallel world where one or two made it, but i doubt you would notice and the world would look identical to the one we live in.
I have always wondered about that. It seems unlikely that a minor difference in the movement of electrons in an atom in another universe will amount to a different life choice than the one I made in this universe. I guess there is the possibility of a radical difference due to a small difference in the movement of subatomic particles, Schrodinger's Cat certainly comes to mind as a (theoretical) example. But I guess in the real world it's more likely that a minor difference will result in no real difference in my life as a whole. But still, even minor differences can have major effects (as I believe Chaos Theory or maybe The Butterfly Effect indicates). However, have you ever wondered if there are major differences between universes, how did you turn out in that universe? Did you marry someone different? Become someone different? Isn't it one of the most fascinating things you have ever heard of? I think one of the reasons (one of many
) that I decided to study Physics is because of a comic book I read many years ago, "What if Spider Man joined the Fantastic Four?" It explained that even though Spider Man didn't join the Fantastic Four in our universe (or should I say the Marvel universe), in another universe, he did. I thought that was a fascinating possibility and I wanted to understand the science behind it. Did any of you have a similar experience?
