Decoherence doesn't defeat quantum uncertainty, it partially hides the multiplicity of other worlds due to thermal connections of the environment. It results inevitably in tracing any single history. Decoherence is why Schrödinger placed the cat in a box, to isolate the experiment from the external observer. The colleague walking in after I have opened the box to observe the cat is also disconnected from the experiment in my description. For them the room is the box. Decoherence still applies to each history. It helps to remember that where Schrödinger's cat paradox shows how the uncertainty of a single electron can be amplified to produce widely diverse timelines, normally the uncertainty of trillions upon trillions of microscopic events entangle to construct a path of history. Decoherence is like placing a mirror in with the cat, the cat doesn't see its own phase space, each branching time line observes a near classical history, while the global superposition of worlds exists beyond the realm of measurement. > "Puppet" implies you are pulling the strings.

I had previously implied a hand puppet, and I was considering the implications of sampling the whole set of many worlds, as if they all exist simultaneously, and in each proceeding moment we find ourselves in one particular universe. This places in question the individuality and will of "observed others" apart from the probabilistic selection of the experienced world. The hand in the puppet is the universe itself. I am undecided on if the observer can bend reality. I don't rule such things out based on skepticism. An individual's will would largely be a product of their personal history, and thus physical events or states, so I do expect a considerable measure of entanglement between the mind/brain and the environment. I will be un-subscribing from this list. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
