"Though quantum mechanics seems to deny the existence of a physical reality independent of its conscious observation, if our observation creates everything, including ourselves, we are dealing with a concept that is logically self-referential — and mind boggling."
(The Quantum Enigma, Rosenblum and Kuttner, Duckworth & Co., 2007).
The vexed question of whether the world exists independently of the conscious mind seems to have settled by the Copenhagen interpretation of quantum mechanics. It seems there is no collapse of potential without observation. It is the act of observation that brings reality into existence — causing an infinite array of possibilities to take up one state or another
There is even the suggestion that new realities can be created by different acts of observation. This may seem far-fetched, but perhaps is not so far from the truth. For we know that we each experience reality differently, each of us has a unique take on the world. And given that different people at different times will see the world in vastly different ways, even ways that are completely incompatible, we could say that there is a valid sense in which we each create our own reality; we each observe a distinct set of probabilities collapsing.
