That's all very interesting, but I'm not talking about the "Multiverse Hypothesis"! I'm talking about the "Multiverse Interpretation" of standard quantum theory, which is something quite different, which it sounds as if you are not aware of. It's not trying to explain existence. It's trying to find a parsimonious interpretation of what is already empirically established. It's trying to explain such things as 2-slit experiments where single photons apparently pass through two slits at the same time. Do we regard "both" protons as real or not? How are quantum computers, which are predicted to be possible by standard quantum theory, able to calculate so quickly except by calculating in lots of parallel strands at once? Parallel reality is implicit in traditional quantum theory: the only debate is how long the other strands last. Please read my last post without preconceptions.Immanuel Can wrote: ↑Thu Jul 29, 2021 2:14 pmQuantum Theory is not the Multiverse Hypothesis. They're two distinct postulates, and the latter is 100% speculative, by definition.
A reminder to any passing browsers: the reason we are discussing this is that standard quantum theory without speculative "collapsing" of other strands of reality is actually a deterministic theory!
