Hi Peter,
You wrote: "Einstein's small space s moving within space S as Hilbert spaces, which may both contain quanta at rest, are implicit in QM but not in SR as presently interpreted."
It's not a matter of interpretation; it's a matter of mathematical domain. The special relativity model is in ordinary Euclidean space; general relativity is in 4-dimensional Minkowski spacetime. N-dimensional Hilbert space -- which is a generalization of Euclidean space -- was chosen for quantum mechanics because our measure space is too small to accommodate quantum superposition. This could be a very long discussion -- in the simplest terms I can muster, states of matter in the Hilbert space based on the "equally likely" hypothesis of probability theory do not correspond to states of matter in spacetime that are deterministic, not probabilistic.
"You can't then say; 1. 'A 'field' can not 'in principle' be discrete', then also 2.' There's nothing novel about the Discrete Field concept'!!"
Except that I didn't say there's nothing novel about the discrete field concept. I said that we're trying to find out if there's anything novel in the discrete field concept. Don't ask me to abandon fundamental principles of mathematics and physics and then congratulate me for understanding.
"It's that very discretion of a 'space', implying boundaries, that is the entirely new concept."
The mere term "space" does not imply boundaries. The Hilbert space is infinite dimensional.
"In fact the 'field' may equally be considered as a cloud, but not just a cloud of individual particles moving THROUGH a space, but as a whole 'inertial system' at rest, where the background is equally moving past the cloud."
At rest relative to what? Here's the problem, Peter -- if you want to invoke a background space, you can't just say abracadabra and have it. This is the problem that Einstein dealt with, in showing that the ether is unnecessary for wave propagation. If you want to restore an ether and call it a cloud, that's okay -- however, you want to be aware that one still has the problem of measuring where a point particle is located in the cloud and how fast it's moving. Then you have quantum theory and the Hilbert space and probability, with the added burden of explaining the physical effects of the cloud. I'm not saying it can't be done -- I'm saying it can't be done with hand-waving arguments and hyperbole.
"i.e. I'm not surprised you find the 'discrete field' concept entirely alien, it is, that is the whole point. And it is ALL about the boundaries."
Again, just using the term "boundaries" does not produce a measured phenomenon nor a mathematical model.
That's the limit of my ability to respond to your post. The tools of relativity and quantum mechanics are not adequate to deal with the issues of nonlinear turbulence that you raise. Maybe you're looking for a complex system model that requires a different approach. Maybe you'll solve the Navier-Stokes equations.
"Now your Question; Waves LEAVING an emitter, say radio waves leaving planet Earth, travel at c wrt Earth until the shock, then travel at c wrt the solar system. So changing speed, just like when arriving. (At smaller scales the 'surface effect' is rather closer). That is a fact from radio telemetry, but until now it's been entirely unexplained. The explanation unites QM and SR."
If such waves are always emitted at c, observed at c, and received at c, whether or not they changed speed when unobserved is superfluous to the physics. I am not aware that there's something we don't understand of radio telemetry -- and I can't see, at any rate, how it has anything to do with uniting quantum mechanics and special relativity.
"The only problem seems to be that mankind struggles badly to assimilate unfamiliar concepts, as you're still struggling now even after clear glimpses, Yes?"
As my wife reminds me from time to time, what seems obvious to me is not necessarily so to someone -- or anyone -- else.
"So does that now resolve the 'c wrt emitter' postulate conundrum?"
What conundrum? Photons are always emitted at the speed of light.
