Stefan,
Good question. Thanks. There's little 'new' in the ontology, I just invoke a heap of 'jigsaw puzzle pieces' and put them together in a coherent way. i.e.
We know electrons (+positrons and protons) have high coupling with EM waves.
In Raman/Compton scattering, for 100 years, we've know electrons scatter at c, which is always be found at c in the electron rest frame (without orbital speed if a 'valence electron'); Raman 1930 Nobel.
We know that electron spin follows magnetic field lines, and flips when reversed.
We have never found a magnetic monopole or actual 'singlet' spin particle. We only know we can only find one direction (clockwise/anti-cwise) at a time, which is equivalent to measuring a hemisphere of a planet.
We know of kinetic reverse refraction experimentally. Only the mechanism producing it has previously not been found.
Non-mirror symmetry of OAM is again well known, but again not well applied.
Helical gauges spin-orbit paths are ubiquitous experimentally (see references).
There are a dozen more effects invoked, but let's consider experimental falsifications; The classical experiment in the end notes has been reproduced and can be again, by anybody.
The model predicts quasar jets should be found at apparent speeds many times higher than c r trigonometrically (yet no local propagation above c). Quasar jets are commonly found up to tens of times higher than c (record so far = 46c).
A timed pair experiment with rotating analysers will falsify the hypothesis. A novel prediction was made that previous time-pair experiments (Aspect and Weihs) should have found significant anomalous data indicating 'rotation' subject to field orientation.
They both did. The data was discarded and ignored as no theory was available to explain it (99.999% of the data in aspects case).
If you'd like to identify any consideration which you feel should be falsified or falsifiable I should be able to pull out multiple citations. I have rather a heap!
Best wishes
Peter
