Could matter and matter waves be derivable?

Physics news on Phys.org
Two EM waves, one propagating outwardly and one inwardly to a sink. Sounds like they're constructing anequivalent to advanced and retarded waves. Not exactly codswallop but not really too exciting either, for me.
 
Interesting feedback complexities - the matrix re-gilded?

The hypothesized spherical-mirror-like communication between 'particles'
seems to provide an interesting environment for information processing and signal broadcast/echo(n)-rebroadcast feedbacks.

Note that integrated echo(n)-rebroadcast feedbacks would occur mutually between all particles in the set in a very complex (and parallell-processor-powerful) feedback system of echoing and re-echoing waves.

It seems to suddenly open up the possibility the universe might be composed from a set of information processing elements, and simultaneously offer a powerful, maybe novel form of CPU design. (Have u noticed things are getting faster slower recently?).

FYI, it is possible to store information in a signal (send it to the moon and back, then detect, re-amplify and re-transmit (rewrite). Delay-lines were used as an early form of computer memory. Thus the system has memory as well as processing capability.

How would the expansion of the universe affect the ever-changing wave-profile of the whole 'organism' as it elaborated over time? Is the feedback processing likely to be at least partyl non-linear? Determinate or non-determinate?
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
