I guess I’ve always been confused by the Many Worlds Interpretation of Quantum Physics and the fact that it’s taken seriously. Like is there any proof at all that universes outside of our own exist?
I admit that I might be dumb, but, how does one look at atoms and say “My God! There must be many worlds than just our one?”
I just never understood how Many Worlds Interpretation was valid, with my, admittedly limited understanding, it just seemed to be a wild guess no more strange than a lot things we consider too outlandish to humor.
Draw a graph by flipping a coin. Start at (0,0). Assume a fair coin and fair flips. Move one unit right each time, but go up (+1) for heads and down (-1) for tails. The line drawn can go arbitrarily far vertically from 0, but the average vertical position necessarily remains 0.
The average position of an electron is slightly more nebulous than the line x=0, and depends on what, if anything, the electron bound to, but for each state an electron can be in there is a group, or a locus, of possible positions that represent that bound state and the whole locus is a mean of sorts. An electron can go on a journey wherever as long as it continues to regress to that locus.
And in the exceptionally rare instance where a subatomic particle goes on an indefinite journey, we call that quantum tunnelling.

I heard about that too. Its absolutely mind blowing when you realise, that we are able to build chips on such a small scale (and not just for special chips but for relatively common chips), that we are dipping into the realm of quantum physics causing all sorts of problems.
