"The speed of light is invariable"
will be replaced with the correct one
"The wavelength of light is invariable".
This means that, in accordance with the formula
(frequency) = (speed of light)/(wavelength)
any registered change in frequency corresponds to a proportional change in the speed of light. In other words, the frequency, as measured by an observer (receiver), shifts ONLY because the speed of the light relative to him shifts.
Some justification for the new axiom:
Albert Einstein Institute: "One of the three classical tests for general relativity is the gravitational redshift of light or other forms of electromagnetic radiation. However, in contrast to the other two tests - the gravitational deflection of light and the relativistic perihelion shift -, you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. [...] The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..." http://www.einstein-online.info/spotlights/redshift_white_dwarfs.html
"To see why a deflection of light would be expected, consider Figure 2-17, which shows a beam of light entering an accelerating compartment. Successive positions of the compartment are shown at equal time intervals. Because the compartment is accelerating, the distance it moves in each time interval increases with time. The path of the beam of light, as observed from inside the compartment, is therefore a parabola. But according to the equivalence principle, there is no way to distinguish between an accelerating compartment and one with uniform velocity in a uniform gravitational field. We conclude, therefore, that a beam of light will accelerate in a gravitational field as do objects with rest mass. For example, near the surface of Earth light will fall with acceleration 9.8 m/s^2." http://web.pdx.edu/~pmoeck/books/Tipler_Llewellyn.pdf
The quotations show that, for light falling in a gravitational field, the frequency and the speed vary proportionally, as predicted by Newton's theory. This means that, in accordance with the formula
(frequency) = (speed of light)/(wavelength),
the wavelength is INVARIABLE.
Here is how the new axiom works:
Premise 1: The wavelength of light is invariable.
Premise 2: The formula (frequency)=(speed of light)/(wavelength) is correct.
Conclusion: The Hubble redshift is due to light slowing down as it travels through space. The universe is STATIC, not expanding.
The hypothesis that vacuum slows down light is largely discussed but only in terms of quantum gravity. The implication that the Hubble redshift might be due to decreasing speed of light is persistently ignored (crimestop).
Sabine Hossenfelder: "It's an old story: Quantum fluctuations of space-time might change the travel-time of light. Light of higher frequencies would be a little faster than that of lower frequencies. Or slower, depending on the sign of an unknown constant. Either way, the spectral colors of light would run apart, or 'disperse' as they say if they don't want you to understand what they say. Such quantum gravitational effects are miniscule, but added up over long distances they can become observable. Gamma ray bursts are therefore ideal to search for evidence of such an energy-dependent speed of light." http://backreaction.blogspot.fr/2017/01/what-burst-fresh-attempt-to-see-space.html
Nature: "As waves travel through a medium, they lose energy over time. This dampening effect would also happen to photons traveling through spacetime, the researchers found. Although the effect is small, high-energy photons traveling very long distances should lose a noticeable amount of energy, the researchers say. [...] If it is true that spacetime is a superfluid and that photons of different energies travel at different speeds or dissipate over time, that means relativity does not hold in all situations." http://www.nature.com/news/superfluid-spacetime-points-to-unification-of-physics-1.15437
"Some physicists, however, suggest that there might be one other cosmic factor that could influence the speed of light: quantum vacuum fluctuation. This theory holds that so-called empty spaces in the Universe aren't actually empty - they're teeming with particles that are just constantly changing from existent to non-existent states. Quantum fluctuations, therefore, could slow down the speed of light." https://www.sciencealert.com/how-much-do-we-really-know-about-the-speed-of-light?perpetual=yes&limitstart=1
