David,
I found your proposals interesting, original and well explained. I also found them reasonable and with some foundation so worth exploring. Of course I would do as much of it resonates very well with fundamental concepts and mechanisms in my own work.
It's a shame you couldn't align the presentation more with the essay topic, however you'll find my own essay uses similar fractal or 'layered' architecture and identifies how 'aims' are emergent from within and from interactions between layers and from feedback loops from quantum scale mechanisms. In this way I think our essays are quite complementary.
Last year I identified the consistency of propositional dynamic logic (layered interleaved or 'modal' logic) with the rules of brackets in arithmatic. That reminds me of interlayer 'rules'. There can be no direct computation between contents of a bracket and the 'next level up', but once resolved, the bracket becomes a key part of the next level, or 'compound proposition' in logic. The layers are then infinite! Can you see a similar structure here?
I particularly liked and agreed with your lines;
"a volume of space has some intrinsic fundamental energy. This is what could give the empty space ("vacuum") a fractal (hierarchical) structure." ..."Uncertainty Principle could be simply a matter of trying to understand phenomena," ... and ; " Both, QM (all things are interconnected) and Relativity (all things are relational), seems to be telling us the same thing albeit from different perspectives which gives hope for a unification."
In fact I also find, identify and explain a coherent small scale physical mechanism CLASSICALLY producing the predictions of QM at the next level up! I do hope you'll get to read and comment.
Great essay, though early days on the model and much current science to review and reconsider (i.e. BigBang & Accelerating expansion theories etc) rather than just trying to build from (I have related work I could link if you're interested). However this is an essay not a scientific paper so doesn't devalue what's worth the high score coming.
Very best of luck.
Peter
