How Two Rebel Physicists Changed Quantum Theory

IIRC the pilot wave theory from Bohmian is good for single particles, but it's difficult to generalize to multiple particles. In my opinion most physicist don't think it's a good idea.

The many-words interpretation of Everett is quite different. I'm still not sure if it's just claiming that the "hallucinated" Hilbert spaces in a measurement are actualy real copies of the "universe".

Disclaimer: I prefer the "shut up and calculate" interpretation, and I hope that "something-something-decoherence" will fix all the problems one day. Perhaps I like "many-words" without knowing.

The main problem with Bohmian mechanics is trying to extend it to quantum field theory

I'm not sure what you mean by "'hallucinated' Hilbert spaces", but MWI is just the combination of the claims that

- The wavefunction is a (the) real physical object

- The Schrodinger equation always holds

- The Born rule is correct (though there's some hope this might be derivable from QM)

The "worlds" are then a statmech phenomenon.

frankly i don’t see at all how decoherence can rescue copenhagen and if anything it seems highly suggestive of a MWI interpretation in practice
