1) Can someone tell me to what extent this many-worlds interpretation is really accepted? I mean, nobody told me the news that the collapse interpretation was no longer accepted, and I think I read such things in a recent physics textbook. So, can physicists remark on their experience?
2) I think the notion that the QM equations don’t mean anything refers to the fact that nobody knows what the real substrate is in which QM takes place. It’s a bit analogous to the pre-QM situation with light. People asked, what does light travel in? But since nobody was able to identify any substrate for light, they had to treat the wave-like nature of light as simply an empty metaphor. At least, that’s how the classical theory of light was taught to me.
So in the same way, you say that the amplitudes and configurations are the “reality.” But where do the configurations “exist”? Unless you believe that the universe is being simulated in a computer (which seems like a highly unparsimonious not to mention anthropocentric assumption), the equations must be a model of something that’s out there. But it doesn’t seem like we really know anything that the equations are models of.
