Dear Philip -
You say: 'The lesson to be taken from holography is that there is a huge hidden symmetry in physics that nobody has yet appreciated.' I agree completely, and I must say that it is interesting in this contest to see how disparate thinkers start from such different perspectives and draw near to a concept of the Cosmos that can, I sense, accommodate a grand synthesis of their views.
Simply put, we're all questioning long the established parameters, as has occurred throughout history - and we're doing so for the same reason as always: so that we might interact with a field of reality that is more comprehensive (or consistent), and less paradoxical.
Like you, I see space-time as emerging from uncertainty - only my paradigm defines certain borders between the states of particles that are projected upon the Cosmos as particles aggregate in large numbers. Consequently, the Cosmos is divided into Zones of dimensionality, as are the particles that constitute it.
This is similar to the holographic interpretation of reality you expound so well, and I wonder if you might not find some use in my paradigm in this regard?
I ask because I work within the broadest set of parameters: Unlike you, my focus is not on the mathematics of the Cosmos, but rather on the evolutionary aspect of both observer and Cosmos, and the effects of their continuous correlation. I submit that it is in this area that our key assumptions must be reconsidered: Is not the historical expansion of mathematics into the field of reality a phenomenon that must also precisely describe the evolution of the human mind within that field?
And is not space-time emergent as a function of evolution, a process that produces our experienced correlation (or symmetry?) in the space-time Zone? If so, symmetry is harder to describe in the quantum world and in deep space - these being the Zones from which space-time and the evolving observer emerge, so that they cannot have the consistency found in space-time, and in the highly evolved mind.
Since information, organism and cosmos emerge from one source and remain correlated (or we could not make sense of anything) my conclusion is that It and Bit are correlated.
I was captivated by your combination of mathematical thoroughness, and your concern for the 'real-world' aspect of whatever paradigm will one day resolve the issues at hand. Given this broad perspective, I'm sure you'll find many points of interest in my essay.
Congratulations on this important work; I have rated it highly, and I look forward to your response.
All the best,
John.
