Dear Avtar,
I hope you will read my essay again, as I do not believe you have understood its potential significance for your work. You dismiss it because you say your photon model depends on special relativity, as it matches the observed universe expansion data. But that is not based on the relativity of simultaneity as you imply. Cosmic microwave background on which all cosmology models are based is essentially Machian, and time is considered absolute with respect to this background. So contradicting "the relativity of simultaneity" does not seem relevant, as it is not involved in cosmological 'universe expansion' models. My impression is that you reached this point and decided not to go further. This is unfortunate, as Hertz's extension of Maxwell's equations address the problem you address, but as "disturbances in the ether", with implied local energy density. Moreover, the recent observation of colliding neutron stars has demonstrated that gravitational disturbances propagate at the same speed as electromagnetic disturbances in the field. There is no "acceleration time" involved!
This Hertzian extension of Maxwell's theory envisions energy flow in a body, while Maxwell/Einstein envisions energy flow between systems. It seems de facto true that cosmology 'universe expansion' observations concern energy flows within the cosmological frame, not asimultaneous flows between frames. (When one frame is the universe, what is the other frame?)
The problem here for your model, is that there is no acceleration. As soon as a disturbance occurs in the field, it immediately propagates at the speed of sound (the generic term for perfect fluid models) - no acceleration.
The significance for you is that this lack of acceleration required to reach speed c implies that light never has value v < c. Of course you refer to recent experiments in which light impinges on a semiconductor material and is absorbed, whence it photons become 'excitons'. In my opinion, such interactions are phonon-like, not pure photons, and are more likely explained as many-body phenomena, rather than pure photons. Of course I may be wrong, there is not enough information to determine this yet. If the phenomenon is essentially one of absorption and re-emission then formulas with the inverse square root of (1-(v/c)**2) are undefined. These are in most of your equations, since you seem to conceive of local 'photon' mass density as a material body, instead of the equivalent mass density of the disturbance in the field. The v-based equations for the photon are inappropriate in the Hertzian framework, which you seem not to have understood in my essay. In spite of this, and for reasons too long to include in a comment, I do find your Postulate 1 on page 5 to be is very astute and appropriate to the problem. It is that which first excited me about your essay.
Some readers, as soon as anything contradicts the received wisdom from Einstein, quit thinking, and dismiss all following information. That is unfortunate. There are a least a dozen interpretations of quantum mechanics, yet all deliver essentially the same calculations. Why should one recoil from a second interpretation of relativity, one that retains the Lorentz equations, but interprets them in terms of energy-time asymmetry, not space-time symmetry?
My best regards,
