I once asked you if you shared Deutsch's interpretation of the MWI in terms of fungible worlds divergent by decoherance, but otherwise invariant in all dimensions a frozen structure, every thing that ever has, and ever will, ever can occur, frozen in little multidimensional capsule. You said you didn't, you saw it differently. I forget precisely what and how. Have you changed your mind at a point between? What was the crucial shift that fundamentally changed the picture for you? Perhaps you are now closely enough aligned with him that you will answer the question that he will not despite many times my asking. Deutsch explains in BoI chapter "The Reality of Abstractions" that abstractions have physical reality independent of dependence of emergent features from underlying, increasingly physical layers So, given independence, that is causal isolation, what is the physical mechanism by which decoherence at the quantum level, will trigger divergence, and divergence will replicate abstract layers that are independent of quantum forces? How does that happen? And if it doesn't happen precisely every single time, how can macroscopic reality be stable? Cause and effect would never endure Second challenge: If the two slit experiment is explained by divergent universes, then the pattern we see in the interval of 'collapse' is therefore the momentary isolation of just this universe as all the others diverge. Which means it should be distinctive in its own right, from what we shall see as the pattern in 'one slit' experiment. Is it? I shall bet it is indistinguishable. Then, is the one slit experiment isolating this universe in some way? -- You received this message because you are subscribed to the Google Groups "Everything List" group.
