"It has a very high frequency, comparable with microwaves."

High frequency as compared with what or by what standard?

Do cosmic rays have an bearing on genetic mutation, and thus Natural Selection?

They might. However, that has nothing whatsoever to do with the CBR. Try Cosmic rays.

Is there enough beef in this article to keep it separate from Cosmic microwave background radiation? --Pjacobi 21:27, 2005 Jan 23 (UTC)

No. All the radiation listed appears to be microwave anyways! –Joke 03:59, 8 December 2005 (UTC)Reply[reply]

Cosmic microwave background or paleophotons or protophotons[edit]


  • paleos + photons = old thermal radiation
  • protos + photons = first thermal radiation
  • archo- /archaeo- + photons [introduced by experimental physicist Giorgos Grammatikakis] = first thermal radiation — Preceding unsigned comment added by (talk) 17:11, 26 September 2015 (UTC) <!- ( mj (talk) 17:13, 26 September 2015 (UTC) )-->Reply[reply]

rare term but used among students

proto-photons has a second meaning - it is a theoretical not yet discovered particle supposedly contributing to gravity - this is a totally separate - not connected meaning

[ask for more]

  • Students may have made this up, but we need to see this used in reliable writings. I did a Google scholar search and found nothing at all. Graeme Bartlett (talk) 00:12, 24 September 2015 (UTC)Reply[reply]
  • I totally agree! Cosmic microwave background is easier to pronounce than protophotons or paleophotons. We must stick to the old name. Students aren't wise enough to be listened.
Students have done all kinds of valuable work on the CMB, including making major contributions to things that are mentioned in the article. They published their work in scientific journals, which are reflected in secondary sources, and Wikipedia uses those. When students try to put things they've made up directly into the article, we welcome them to Wikipedia and invite them to help build the encyclopedia (but remove the made-up stuff). If you'd like to help improve CMB articles, I'd be happy to suggest some tasks that would be really helpful. --Amble (talk) 15:21, 24 September 2015 (UTC)Reply[reply]

Most of the microwave content should be in that article with a hatnote as most readers probably want that one[edit]

This should be more like a short page with anything that's better on this general page than specific ones like neutrino background radiation. Sagittarian Milky Way (talk) 20:52, 12 January 2021 (UTC)Reply[reply]

Cosmic Gravitational Wave Backgound[edit]

There appears also to exist a cosmic gravitational wave background

A notice might be placed in the article by an expert. Thanks! --Ernsts (talk) 10:56, 14 January 2022 (UTC)Reply[reply]
