Talk:Red shift

The article might better be called "Doppler Effect", which accounts for red shift and blue shift of electromagnetic radiation.  Rational Ed think! 12:07, 22 May 2008 (EDT)
 * As it's in the context of showing the expansion of the universe, I think blue shift is fairly irrelevant. Red shift is the commonest usage in this context. Doppler effect includes any form of wave radiation including sound - this would dilute the intent. Rather have another article Doppler shift & cross refer? 12:17, 22 May 2008 (EDT)
 * The above is a good argument for covering red shift separately, due to its relevance to cosmology, but not on a separate article. Scarlet A.pngmoral 10:35, 29 January 2012 (UTC)
