What follows is an exercise in pure logical deduction based on parameters that are not necessarily well defined, but accepted as part of the standard model in particle physics.

Copenhagen interpretation says that a system stops being a superposition of states and becomes either one or the other when an observation takes place. Schrödinger through his cat, Link showed meta-physically, that a state can be any number of states, but not necessarily observed directly for it to be true. In my opinion, the realization and cognizant function of the observer, is only directly related to the state of the observer, and thus, any other interaction that changes the existential state of that interacted with.

Take Wigner's friend, but go further than that; assuming that "friends" need not be tied quantumly as entirely dependant of each other for it to be true. In this scenario, the friend carries through the wave-function of the state. The state being whatever the cat's state was after opening the box. Now applying Everetts Many World Interpretation, we now have a dilemma; the dilemma being that if Everett is correct and parallele universes exist, then what would happen if Wigner's friend met it's identical (Parallele universal) Wigner?

For example, whether the cat is dead or alive is directly related to the instant observation, and thus, as a direct extrapolation, said to be only static when observed; or observable only when directly measured. For instance, if Wigner was the observer and the cat was dead, he carries the wave-function to that of the cat being dead at that monent of observation. At this time, a parallele universe is set in motion, where at the parallel moment of the observation, Wigner would have obsered a living cat. Now, Wigner's friend, likewise, observes the cat being dead, like the instant (Wigner alive scenario) observation, and he too begins a parallel universe where the cat is alive. Now, assuming there are no barriers to dual wave-functions beng carried on identically in the same universe, then time becomes the issue of observation.

This refutes Schrödinger's cat because both universes require that time separate the two oberservations, but time itself does not preclude the interaction of the parallel friend of Wigner, nor the parallel Wigner himself, yet, it must, if one assumes that parallel states are dependant on the instant of time, and decoherent of each other. If one agree's that this is absurd, then it is true that the Copenhagen interpretation is in fact true and states become such only when directly measured or observed.

Thoughts?
