@ Angie_: awesome posts all through!
i think there's a whole lot of ambiguity about consciousness. Is it information? Is it the ability to have some degree of interior experience? It seems to me that every organism that is sensitive to it's environment has that. The cat, the dog, the bacterium that responds to external stimuli or physical vibrations. It is actually our ego that makes us think we are unique in having consciousness, but who are we to say that other organisms do not have at least a small degree of consciousness..Where too do we draw the line...
it also seems to me that consciousness is very closely related to free will. If everything was physics, where is the possibility of a free agent that can intercede in the middle of the cause-effect cycle and affect anything? We would then have external stimuli affecting brain activity, creating thought and images in the mind as a by-product. No transmission the other way around. In fact, we would have a world that theoretically would be deterministic, in the sense of being entirely predictable if we could ever have that processing power.
the other aspect that i think relates to all this is the uncertainty principle. It makes the world probabilistic, thereby introducing unpredictability. Does it tie in with the sense of conscious experiences? Also, is the unpredictability a fundamental feature or is it because of our inability to compute anything beyond a probabilistic curve? I think the amazing thing here is that apparently there is uncertainty not only at the particle level but also at large-scale macro levels.
beyond that, i think if we drill down into every particle, even those considered elementary today, we might find them to be energy... or at least analogous to energy. So while we are happily making distinctions between the physical world and the virtual one of our minds, it might well be the case that they are both fundamentally different manifestations of energy. Energy that can be stored at different locations/ reservoirs, energy that can transform, energy that is conscious of itself and energy that can respond to other energy (much like energy differentials)... Just a bunch of random thoughts i know... but somewhere i feel that all these aspects are intertwined, much as would be the case in a holographic universe...
