Simple declarations make no sense. One should, as John von Neumann has done, merely rely on the unambiguous mathematics constituting quantum theory. The quantum mechanical time evolution is valid for all "physical systems". That's the reason why all “quantum processes” finally boil down - in mathematical language - to something like a purely quantum-mechanical von Neumann measurement chain when physical systems are interacting which each other.ObjectivelyRational said:Trying to play philosophical games about reality rewriting itself once you "consciously" are aware of it.. that is sensationalism, not science. Quantum processes occurred in the universe countless times over billions of years before human consciousness existed, and they are occurring and "resolving" in over billions and billions of light years (cubed) of space and in billions and billions of galaxies through out the vast cosmos without a need for any consciousness to collapse anything.

And what happens at the end of such a purely quantum-mechanical von Neumann measurement chain? In case the “observer” is regarded as a “pure physical system”, mathematics is unambiguous: Nothing happens; the “purely physical observer” is simply part of the purely quantum-mechanical von Neumann measurement chain and entangles with the system the state of which is to be measured! The system is sucked into a vortex of entanglement and no longer has its own quantum state. On top of that, the entangled state fails to indicate any particular measurement outcome.
