Havriliak:

Thanks for suggesting some questions.

The issue of the Red Shift when understood in terms of the Doppler effect can explain the "motion" (Hubble's term) away from the viewer of celestial objects, for example. Its corollary, the Blue Shift, explains the motion of objects towards the viewer.

Rayleigh's light scattering theory has nothing to do with that. He did provide the explanation for the elastic scattering and backscattering of blue light in the sky of air. That is not the Blue Shift. To say that the two are the same would be an equivocation on the facts.




Blue shifts occur in a number of object such as
glob-clusters and galaxies.  In the former case the blue shifted light
from a glob. is considered to come toward us.  In the case of galaxies
that rotate, the red shift of the edges is assumed to be travelling
away from us while the blue shif indicates the tip is rotating toward
us.



That is true, and the Doppler-Euclid-Hubble theory nicely explains that.
One has to differentiate ordinary Doppler Effects from the Doppler Effect used to explain a general cosmological expansion.

The light photons from distant objects have been clearly identified to have reduced energy levels. That is sufficient to explain the spectrographic Red Shift. Hubble ultimately reversed his opinion, and he said that there was insufficient and inconsistent evidence to conclude that there was a general cosmological expansion. He said that there was evidence that showed that the reduced energy level of photons may be due to other causes, and that those causes should be investigated by other scientists who are concerned with those matters.



    Also I thing there was some work showing a gradient of shifts
across the galaxy.




The Cassini results also show that the IR energy levels vary, and that the uneven-ness of IR radiation energy levels is probably due to the interactions of photons and hydrogen, and the varying amounts amounts of hydrogen. The more hydrogen the photons collide with mean that the energy level is reduced more. The scientist's reports and conclusions must be consulted for a proper explanation.
