The discussion centers on the Many-Worlds Interpretation (MWI) of quantum mechanics, specifically addressing the concept of non-locality and how observers in different worlds can correlate their measurements. It is established that worlds separate through decoherence, which propagates as a sphere at light speed, leading to splits only within intersecting future light cones. The participants clarify that MWI operates in a 3N-dimensional space, where N represents the number of particles, rendering it "alocal" rather than strictly local or non-local. The correlations between measurements in different worlds are inherent in the wave function's structure, negating the need for additional synchronization.
PREREQUISITESPhysicists, quantum mechanics students, and philosophers interested in the implications of the Many-Worlds Interpretation and the nature of reality as described by quantum theory.
Indeed so but that's a weaker sense of ontic than I was using. I was just meaning that there is no reason why reality must actually be the wavefunction. A 1-1 map would be fine.akvadrako said:The reason the wavefunction must be ontic (which that I mean maps 1-to-1 onto reality) is given by the PBR and Colbeck and Renner theorems.
