New Twist on Hubble's Law

There are three ways, using standard physics, to explain the redshifts and the blueshift of light: Doppler effect, gravitation (low!) and CREIl which is the result a parametric effect resulting from several simultaneous, impulsive, space-coherent Raman effects. Energy is transmitted by this CREIL effect in conformity with thermodynamics, that is from hot to cold, the temperature of light being deduced from its radiance and frequency by Planck's law. In the labs, the CREIL effect is easily observed using femtosecond laser pulses, or with longer pulses in optical fibres. In space, the required matter is atomic hydrogen in 2S or 2P states, the cold rays are in the thermal backgroung (or the radio signals pf the Pioneer 10 and 11 probes); the need of excited atoms of hydrogen explains that the high redshifts are observed for or around extremely hot stars (quasars, supernova).

Since the velocity of a wave is f*w, then a drop in v means a drop in f, and walla, redshift, which is an observed phenomenon.
You say,
"Since the velocity of a wave is f*w, then a drop in v means a drop in f, and walla, redshift, which is an observed phenomenon."
This does not really follow.
In refraction when waves slow down, f remains the same but it is wavelength that decreases - and in cosmology it increases!
just a thought,

I'm not talking about refraction though.
I'm talking about Hubble redshift being the result of a new property of light.
That seems much simpler than causing space to expand and move every galaxy away from each other.

So, in your theory, does light slow down at the beginning of its journey or the end?
BTW, why should it be different anyway?

The CREIL effect is due to an exchange of energy between light beams, generally between light (redshifted) and the microwave background (blueshifted). The effect works all along the path. It is too weak (except using ultrashort lightpulses) to be observed along a short (laboratory) path because the length of the pulses (length of coherence with ordinary light) must be shorter than:
-The collisional time, so that the pressure must be low enough to get paths free of collision along several metres.
-A quadrupolar frequency of the gas. Atomic hydrogen must be excited because the 1420 MHz resonance has a too short period.

To be honest, I don't see what this has to do with the OP.
But, in Creil, photon - photon collision cross sections are known, photon densities are known. Must be a simple calculation to work out an expression for the Hubble constant and Whallah! test it by putting numbers in.
Have you done this?
