Notified: ජපස, Praemonitus, Marisauna, Iantresman, Art LaPella, Vsmith, AP Astronomy, WP Physics, WP Color, WP Measurement, original notice in January 2023

Since the original notice in 2023, there have been periodic comments on the article's talk page regarding sourcing and other issues, including one from January raising possible OR concerns. There are 9 CN tags in the article. This is one of the last 48 remaining pre-2007s to be at the WP:URFA/2020 listing. Hog Farm _talk 04:09, 5 March 2025 (UTC)[reply]

I worked over the History section using secondary sources and removed my OR concern. Johnjbarton (talk) 20:14, 6 March 2025 (UTC)[reply]

I have provided citations for all the remaining CN tags. jps (talk) 22:02, 6 March 2025 (UTC)[reply]

Fixed and removed "broken anchors" template. PianoDan (talk) 00:20, 7 March 2025 (UTC)[reply]

I just added a note to the talk page, encouraging a review of Tong's textbook "Cosmology" which points out that even Hubble and Silpher, credited with discovering that redshift correlated with distance, did not understand that this implied an expanding universe. Apparently, they called it the "de Sitter effect" for a while; it took a while to figure out that galaxies are receding because the universe is expanding (and they were not the ones to figure this out). Science is non-linear. The obvious, canonically-accepted answer today is usually confused and muddled when first stated. 67.198.37.16 (talk) 00:43, 15 March 2025 (UTC)[reply]

I suggest that this interesting aside is probably best left explained at the expansion of the universe article. Redshift is an empirical phenomenon, and the interpretation that it is due to metric expansion deserves some economy on a page dedicated to the observable shifts of light rather than the history of how such shifts were interpreted. jps (talk) 23:29, 24 March 2025 (UTC)[reply]

Johnjbarton - Do you have any further thoughts on this? Hog Farm _talk 21:36, 6 April 2025 (UTC)[reply]

I replied on Talk:Redshift#Redshift_as_the_"de_Sitter_Effect" as in my opinion this suggestion is for a minor addition to Redshift which is not well connected to the topic based on the sources we have. It's more about Hubble's Law and in any case not a showstopper for FAR. Johnjbarton (talk) 00:30, 7 April 2025 (UTC)[reply]

Could we get an update on status here? Nikkimaria (talk) 14:17, 19 April 2025 (UTC)[reply]
