I (Iantresman) have copied this entry directly from the Talk:Intrinsic_redshift page:
I don't have time for prolonged bickering about this topic. There is research published in professional astronomical journals that discusses the topic of intrinsic redshifts. Ian has linked to those articles. That alone is enough to justify the existence of this article. As for the writing of the article - that is something that can progress. I don't think it is unfair to make sure that the article states that the hypothesis of intrinsic redshifts is a speculative, minority view. However, there is a use in having this article as a reference to what an "intrinsic redshift" might be.
One of the difficulties is that there are a lot of different controversial redshift mechanisms and some of them may be "intrinsic" and some of them are not. For clarity it should be understood that the Hubble relation defines the cosmological redshift. Expansion of the universe is the accepted mechanism for cosmological redshift. Tired light mechanisms provide another attempt to explain cosmological redshift.
Intrinsic redshift specifically refers to variations in the observed redshift of individual objects (galaxies, quasars ... ) that vary from object to object such that two objects at the same distance might have vastly different redshifts. Note that "intrinsic redshifts" - if real - may be superposed upon the cosmological redshift. So properly speaking, anything that attempts to explain all of the observed redshift as cosmological (expansion, tired light) belongs in the main "Redshift" article - or an article titled "cosmological redshift". Any redshift mechanisms that are superposed upon the cosmological redshift defined by the Hubble relation would properly belong in the "intrinsic redshift" article.
I see no reason to provide any edits to the article until this issue of its existence is resolved. --DavidRussell 18:06, 2 January 2006 (UTC)
