Dear Wilhelmus de Wilde,
It's been obvious for years that you are extremely focused on consciousness, so I'm not surprised.
I very much like "searching for the announcer in the radio".
When I first read your essay I started to give you 10, but everyone I pushed to the top so they would receive more visibility immediately got shot down by whatever troll lurks beneath the FQXi bridge biting passersby with 1's.
Also, I wanted more time to digest the meaning of your essay. While I think your scheme is magnificent, I was unsure how literally you meant it. For me experience of physical reality is key, but current projections of structure on physical reality are confused at best. Essays on consciousness seek to gain 'respectability' (the coin of the realm) by tying their systems to physics (the holy word of the realm). If the physics is mistaken (as much today is) it can take a perfectly good understanding of metaphysics in the wrong direction.
You work your way through various physical concepts and introduce 'limits', the speed of light and Planck time and length, then concede that Planck units do not exist in reality as we experience it. I would instead choose the speed of light and Planck's minimum interaction, h, both of which do exist. The Planck time and length are derived units, which, as you say, are unreal. My argument is for a physical continuum, not captured by mathematics, but closely approximated.
So I see the Planck Wall as a mathematical projection, having no physical reality. [In fact, you compare it to an abstract mathematical structure: Hilbert space.] You then construct an abstract 'space' called Total Simultaneity, based on the conception of Eternal Now Moments. I tend to view our universe as existing in one ENM, and all local consciousness partakes of this Now.
I do not buy the Copenhagen interpretation (or any other current interpretation) of quantum mechanics so I don't see observers as 'collapsing' a superposition of wave functions, and "creating" reality. QM is a statistical theory that describes averages when particles with always-associated-wave properties experience different paths. The idea that they experience this all-at-once as a superposition of probabilities is a projection I do not buy into. As I said in my essay: the statistics work, it is the interpretations that are in error. As you note, most experiments have been performed with photons, not particles, and certain aspects of photons have been unclear since Planck. I will not be able to resolve these in the comments. Nevertheless, I do not accept 'retrogression' as an acceptable way around built-in errors. Neither is this the place to argue entanglement. For more info, see:
Spin: Newton, Maxwell, Einstein, Dirac, Bell
I do believe in a physically real universe, but GR and QM have confused the issue via erroneous projections that are (at the moment) given credence. The universe will not simply vanish when these errors are corrected, but certain mystical and unphysical conceptions will vanish.
In short, I think you've developed a powerful way of describing the experience of local conscious beings in a unified reality existing Now. I think you should not try to tie it too closely to mystical elements of current physics which will not survive the century. Hopefully, not the next decade. As metaphor I buy your beautiful system. As physics I do not buy it. Clearly, over the sequence of FQXi essays, you are getting closer to the truth. I am sure you will continue to do so. By the way, I chose your figure 1 as the cover for my first book on consciousness, Gene Man's World, ISBN-13:978-0979176555.
My very best regards; keep up the excellent work.
