For example, many-worlds theory does not explain why we get only one result on any measurement,/*A measurement is performed by an intelligent agent, and like everything else in the universe that agent is a quantum object. According to Many Worlds when an electron goes left instead of right, even though both possibilities are allowed by Schrodinger's equation, the electron splits but that's not the only thing that splits, so does everything else that interacts with that electron, *
That's the tricky part. Decoherence explains how a world in which the spin is UP becomes orthogonal to a world in which it is DOWN. But being UP v. DOWN is probabilistic and one can as well phrase it as decoherence makes the superposition unstable so that it falls into either UP or DOWN but not both.
