Bruno, Glad we agree that decoherence falsifies collapse. That's a good start!

But decoherence also falsifies MW. First of all you have to understand what a wavefunction is. It's not a physical object. It's a description of a physical object in human math. Basically in QM its formulated as the 'answer' to a question that can be asked about a physical object. Second, properly understood, there are no 'branches' to a wavefunction. The correct interpretation of a wavefunction is not a description of a physical object (electron) smeared out in a fixed pre-existing background space common to all events, it's a description of how space can dimensionally emerge if that particle decoheres with some other particle, in other words it's the range of possibilities for the dimensional relationship that would occur if it interacted with another particle's wavefunction. Thus all this occurs not in physical space, but in logical computational space. It is only when wavefunctions actually interfere and decohere with each other that actual dimensional relationships arise, and therefore a point in a dimensional space is created. This is how dimensional spaces emerge piecewise from quantum decoherence events. So you do get many individual spacetime fragments emerging out of logical computational space by this process, but they are not separate universes, because they in turn continually merge via common events that connect and align them. The result of googles of these processes is the simulacrum of classical spacetime. It is the origin of physicality from computational space. That's the way it works.... And this model also unifies GR and QM and resolves all quantum 'paradox' at the same time, as well as explaining the source of quantum randomness, so it's an excellent model. You really need to understand it. Everett had an insight but since he didn't understand how spacetime emerges from, is actually created by, quantum events in computational information space, he followed it off into never never land...
