Featured Article?

How come Redshift is an featured article while this one is a stub? Isn't it the same phenomenon only that they are each others opposites? Perhaps a merge? —Preceding unsigned comment added by 81.228.228.224 (talk • contribs)

The Redshift article is extremely well-sourced, and has lots of illustrations and context. A merge would not be a bad idea. --Kuzaar^-T-C- 11:41, 16 August 2007 (UTC)[reply]

It is strange anyway. People must prefer red over blue or something :P. Soon2Bregistered 81.228.228.224 17:53, 17 August 2007 (UTC)[reply]

Perhaps because this article isn't currently very good? ErkDemon 02:20, 3 September 2007 (UTC)[reply]

I added a little bit about the limit to blue shift, makes the article a little bit better I think. Feel free to elaborate.--MaizeAndBlue86 (talk) 00:28, 23 February 2008 (UTC)[reply]

Isn't there a collective term for red shift and blue shift which could be used for an article replacing these two? — Preceding unsigned comment added by 82.71.43.37 (talk) 14:00, 3 February 2012 (UTC)[reply]

I would say the generic term is "redhsift". I'm not sure why this article exists at all. Thirteenangrymen (talk) 22:18, 7 June 2016 (UTC)[reply]

Redirect to redshift

Why was this redirected to redshift? None of the information here was merged to that article. 70.51.9.237 (talk) 11:35, 9 July 2008 (UTC)[reply]

If the information was useful and non-overlapping, perhaps get it from the history and upload it on the redshift? Headbomb {ταλκ – WP Physics: PotW} 12:12, 9 July 2008 (UTC)[reply]

Limit of blue shift

According to well accepted quantum theory, the limit of blue-shift is approached when a half-wavelength of light approaches the planck length. This corresponds to a half-wavelength of 1.616x10^-35 meters, and a frequency of 9.276x10^42 Hz (and defines a minimum period of 1.078x10^-43 seconds, which therefore must be the minimum increment of time in the universe).

Blueshift

Should this article not be renamed to blueshift? Redshift is one word. —Anonymous Dissident^Talk 04:16, 4 October 2008 (UTC)[reply]

Stub

This is relatively minor, but shouldn't there be something on the bottom labeling this article as a stub? —Preceding unsigned comment added by GundamMerc (talk • contribs) 02:34, 17 February 2009 (UTC)[reply]

Move from blue shift

Moved blue_shift to blueshift as there is no space between blue and shift in the cited articles. see also: http://www.astro.virginia.edu/~jh8h/glossary/blueshift.htm

Also, dropped 'known' in 'known possible causes' as that is an oxymoron. --Torsin (talk) 17:27, 26 January 2011 (UTC)[reply]

Cosmological blueshift section

The section on "cosmological blueshift" appears to be nonsense. No supporting references are provided. I suggest it is deleted. Thirteenangrymen (talk) 10:45, 7 June 2016 (UTC)[reply]

This appears to have been rewritten and is no longer contentious Thirteenangrymen (talk) 09:10, 24 July 2018 (UTC)[reply]
