: According to the Copenhagen interpretation the original (1) and final (3) z-axis spin measurements have only a 50% chance of agreeing because the intervention of the x-axis measurement by the conscious observer (the machine) caused the collapse of the electron's wavefunction. According to many-worlds the first and third measurements willalways agree, because there was no intermediate wavefunction collapse. The machine was split into two states or different worlds, by the second measurement; one where it observed the electron with spin "left"; one where it observed the electron with spin "right". Hence when the machine reversed the second measurement these two worlds merged back together, restoring the original state of the electron 100% of the time.
:
: Only by accepting the existence of the other Everett-worlds is this 100% restoration explicable.

То есть событие (the second measurement) происходит, затем оно оказывается стертым? - но это противоречит калссической логике (см.: G. Quznetsov "The Poincare group deduced from the logic properties of the information"
in "Photon : Old Problems in Light of New Ideas", ed. V.V.Dvoeglazov (Nova Science Publishers, NY 2001)или http://arXiv.org/abs/physics/9901039). Если событие произошло, то по логике его уже никак не стереть, не возвращаясь в прошлые времена. А отказываясь от логики, мы получаем уже не Science Fiction, а просто Fiction. Id est: либо верим, либо не верим. |
