I have outlined by views on this several times on this forum. I do not favor one interpretation over another based solely on logic. I am very skeptical of any kind of “objective collapse” for the same reasons Eliezer is, because in the EPR setup (singlet decay) it would require some sort of correlation between spacelike-separated processes. But stranger things have happened to physics, so who knows. For the same reason I am also skeptical of the naive MWI, since the two pairs of split worlds would have to “recombine” in just the right way to produce only two worlds when the measurements are compared. I am slightly partial to Rovelli’s Relational QM (Eliezer hates it), because it provides an explicit ontology matching the shut-up-and-calculate non-interpretation (unitary evolution + Born rule), without postulating any invisible processes, like collapse or world-splitting. I think that Bohmian mechanics is extremely unlikely to reflect the “reality” (i.e. the potential future model one level deeper than the present-day QM), if only because it’s so clunky.
As I said before, we have no good model of how a single observed eigenstate emerges during an irreversible multi-state interaction (known as the measurement), and this biggest mystery in all of quantum physics deserves more research. The magic incantation “MWI” is a curiosity-stopping spell, which might be interesting in the HPMoR universe, but has no value in the one we live in.
Thanks for the answer! I wish someone would explain to me RQM in simple terms, then I could make an opinion about it.
I know this probably doesn’t sound good, but I remember reading in Feynman’s book how when he was talking to mathematicians about complex mathematical things, he tried to imagine a specific object, like a ball, and then apply what they said to that specific object; and if didn’t make sense, he objected. I am essentially trying to do something similar, but with the concepts of physics. So I’d like to hear a story about what happens with the ball in the MWI multiverse, and what happens in the RQM multiverse. (I am not asking you specifically do to that, I just express my wish.)
