There are no numbers on those "axes" so you cannot tell if they are linear in frequency, wavelength or what.This means that you cnnot interpret them in the way you seem to have done without further data.

Anyway, if the red shift depended on frequency, I think they would have already noticed it and it would already be in all astrophysics books.

Red shift differences between pairs group around 72, 144 and 216 km per second. Probability theory tells us that there are only a few chances in a thousand that such clumping is accidental. In 1982 an updated study of radio pairs and a review of close visible pairs demonstrated this same periodic pattern at similarly high significance levels.Radio astronomers have examined groups of galaxies as well as pairs. There is no reason why the quantization should not apply to larger collections of galaxies, so redshift differentials within small groups were collected and analyzed. Again a strongly periodic pattern was confirmed.

Several ways can be conceived to explain this quantization. As noted earlier, a galaxys' redshift may not be a Doppler shift, it is the currently commonly accepted interpretation of the red shift, but there can be and are other interpretations. A galaxys' redshift may be a fundamental property of the galaxy. Each may have a specific state governed by laws, analogues to those in quantum mechanics that specify which energy states atoms may occupy. Since there is relatively little blurring on the quantization between galaxies, any real motions would have to be small in this model. Galaxies would not move away from one another; the universe would be static instead of expanding.This model obviously has implications for our understanding of redshift patterns within and among galaxies. In particular it may solve the so-called "missing mass" problem. Conventional analysis of cluster dynamics suggest that there is not enough luminous matter to gravitationally bind moving galaxies to the system.

You will need better proof than the statements of a book to prove that idea.Are there no astrophysicists on this site that know of any such links?It would be interesting.

I just did a Google search with the phrase: samples of red shifted spectrumGuess what was number two on the list [] That is kinda swift, since I just started this thread this morning.

Hi Vern.Redshift z is the ratio of delta lambda /lambda. In the BB, Ashmore redshift and observation, photons of light at the red end of the sprectrum are shifted more than those at the blue end such that the ratio delta lambda /lambda ie 'z' is constant, This is not a problem for either me or the BB.Cheers,lyndon

The sums are very straightforward. There are two calculations you can do; one is non-relativistic and the other is relativistic. The relativistic is obviously what counts for red shift. Browse around for a link that suits you, sir.

Browse around for a link that suits you, sir.I don't have any problem with the calculations; the problem I have is understanding why the equation should be z = delta lambda / lambda for a Doppler shift. I guess I'll just have to work on it.
