GA from 2015 that have multiple problems. I posted this comments 20 days ago, but it seems that nobody is willing to update that article and thus GAR is required.
The article is not bad, but currently lacks citations is several sections. Chronology and the Big Bang is mostly unsourced, with cn and clarification needed tags. Physical properties uses really strange source ("Antimatter". Particle Physics and Astronomy Research Council", see citation 44). Age and expansion ends with a strange sentence This acceleration does not, however, imply that the Hubble parameter is currently increasing; see deceleration parameter for details.
Spacetime has unsourced sentences. Support of life is just a few sentences with really strange sourcing: "Isaak, Mark, ed. (2005). "CI301: The Anthropic Principle". Index to Creationist Claims." (see citation 78). Halfs of Dark energy and Ordinary matter are unsourced. Same for Hadrons.
Historical conceptions are also problematic. Half is unsourced, and the sourced parts are often built on really old sources: see "Stcherbatsky, F. Th. (1930, 1962)" (citation 152), citation 13 lacks year and page, cit 150 lacks year. Astronomical concepts is either unsourced or sourced to "Aristotle; Forster, E. S.; Dobson, J. F. (1914)"; the article abruptly ends with The modern era of physical cosmology began in 1917, when Albert Einstein first applied his general theory of relativity to model the structure and dynamics of the universe.
with nothing about modern era.
There is also a question on talk page about the audio version being outdated (13 June 2012 (!)) - maybe it should simply be removed? Artem.G (talk) 17:39, 6 February 2023 (UTC)
- I think a public-outreach website from the Particle Physics and Astronomy Research Council is a decent source for a general statement like that, all things told. It would be nice to have a citation that isn't an archived copy of a web page, and we can swap it out, but I wouldn't stress over it. The Index to Creationist Claims is probably also OK for mainstream scientific responses to pseudoscientific nonsense, and thus for short summaries of mainstream positions on out-there speculation. In "Ordinary matter", the stuff about four familiar phases plus BECs and such is standard, and a decent college textbook would be a reasonable source. I will try to dig up the Allday book which is cited in the "Hadrons" section; it might cover that whole paragraph already. XOR'easter (talk) 13:41, 14 February 2023 (UTC)
- It occurs to me that we recently put Planet and Solar system through successful FA reviews, and the historical material in those could also be applicable here. It took a long time for the Universe to be recognized as a much bigger thing than the solar system, after all. XOR'easter (talk) 15:32, 14 February 2023 (UTC)
- I removed the last remaining cn from the Chronology section after adding links to the flatness and horizon problems, which were being alluded to, but unclearly. These are quite complicated ideas and so best not to attempt to summarise in a sentence or two. PaddyLeahy (talk) 00:28, 20 February 2023 (UTC)
- Well, it's in better shape now. I'll leave it for someone else to decide whether it is "Good". XOR'easter (talk) 19:46, 27 February 2023 (UTC)
- Keep looks good, and I trust XOR's knowledge more than my own ability to assess. ~~ AirshipJungleman29 (talk) 22:14, 2 March 2023 (UTC)
- Keep, thanks to XOR article looks better now! Artem.G (talk) 10:30, 4 March 2023 (UTC)
I would like to propose changing the lead image of the article.
https://commons.wikimedia.org/wiki/File:Hubble_ultra_deep_field.jpg#mw-jump-to-license This is because this image looks more accurate to look at and is reliable enough to be selected as a recommended photo by Wikimedia Bluesky0750 (talk) 05:28, 30 March 2026 (UTC)
- The proposed image and the current one look almost the same and both are marked as WP:Featured pictures. Why would we change? Johnjbarton (talk) 15:08, 30 March 2026 (UTC)

Please Change "Since the early 20th century, the field of cosmology has established that that the universe has been expanding for 13.8 billion years, starting from a dense fireball in an event called the Big Bang." to "Since the early 20th century, the field of cosmology has established that the universe has been expanding for 13.8 billion years, starting from a dense fireball in an event called the Big Bang."

Done Thank you. Annh07 (talk) 07:56, 20 May 2026 (UTC)
Leptons? Really?
Why does this article have a section on Leptons?
I propose to Delete the section on Particles as off topic. Sure, we could include every single topic in Wikipedia in an article on Universe, but that is not how sources talk about the topic. Johnjbarton (talk) 22:54, 8 August 2026 (UTC)
