I am approaching Many Worlds interpretation and I have a big question that I would like to ask you:
I buy the critic moved by Many Worlds supperters to Copenhagen interpretation, saying that Bohm theory is not providing any detail about "under which conditions" the wave function is supposed to collapse. I buy this. But, switching to Many World theory, I also cannot find the answer to a similar question: under which conditions the branching happens? Because if we consider branching at very low level, we can easily say that if we consider an electron whose spin can be left or right, we have two worlds' branches. But, man, it means that for like 0.01 second of my life, 100.000.000 branches of my world are created, one for each permutation of left/right of all electrons that I am made of. Just for 0.01 second of me. And we are juts considering myself as a system, while my world is me, people sitting next to me (with their atoms), the chair (with its atoms, branching for spin left and right), etc etc. So, it seems...simply too much for being considered interesting and valuable. Or maybe branching is happening only under certain conditions? Like only a conscious observer is observing? But if this is the answer, why do we need a conscious observer? Doesn't seem too much human? That's where I'm getting lost. I would really love your point of view on this.
