Decoherence as Projection
Peter_Mexbacher10

I asked this question in the Born Probabilites post but it didn't get answered so I try again because I think it is important, and it concerns decoherence so it fits here:

A major problem with Robin's theory is that it seems to predict things like, We should find ourselves in a universe in which lots of decoherence events have already taken place," which tendency does not seem especially apparent. Actually the theory suggests we should find ourselves in a state with near the least feasible number of past decoherence events

I don't understand this - ... (read more)

I don't understand this - doesn't decoherence occur all the time, in every quantum interaction between all amplitudes all the time? So, like for every amptlitude separate enough to be a "particle&q... (read more)

I'd also love to know the answer to Peter's question... A similar question is whether we should expect all worlds to eventually become mangled (assuming the "mangled worlds" model). I understand "world" to mean "somewhat isolated blob of amplitude in an amplitude distribution" - is that right?
