What proof is there of the multiverse? (sh.itjust.works)

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.

Because trying to overturn a century of scientific consensus is definitely controversial, at best.

I don’t think what I’m suggesting is “trying to overturn a century of scientific consensus”. It’s a mildly different interpretation of the same math, that doesn’t require many physical worlds. It’s also not that uncommon. The “many worlds” idea is not scientific consensus. Go read about interpretations of quantum mechanics from sources other than Sean Carroll.

How, specifically, are you modeling the double slit experiment using only Newtonian Mechanics? How about quantum tunneling?

Both the double slit experiments and quantum tunneling emerge when you apply quantum statistics to any point particle following Newtonian mechanics.

Are claiming that super positions don't actually exist at all? Because, again, you'd better have a solid argument for such a radical claim.

Superpositions are a mathematical tool for describing the statistics of potential measurements.
