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There is also a question on talk page about the audio version being outdated (13 June 2012 (!))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?

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.

While spacetime is a technical term, the universe is spacetime and its contents. The interaction of space and time is part of science (see theory of relativity). Therefore, link spacetime and write space and time. Space and time should remain to aid nontechnical readers. Besides, space and time are everyday words which shouldn’t be linked per WP:OL.

I think linking the tactile concepts is much more helpful and intuitive for a general audience. Your conception of WP:OL is also a hair too broad and dogmatic: links are a navigation aid, so every article has other articles whence it can be linked: normally space and time shouldn't be linked, but they should be from here, as their encyclopaedic substance is directly relevant.

In the context of the universe, space and time means spacetime. While a technical term, it is the correct term. It is technically incorrect to consider space and time as separate, which is what separate links imply. Additionally, space and time redirects to spacetime.

I don't think this argument here is very robust or coherent, sorry. We're not operating in a particular technical frame, we're operating in a general, encyclopaedic frame.

TLDR for 3O
While we both agree the first sentence should be: "The universe is space and time and their contents.", we disagree on how linking should occur for "space and time".
My opinion: space and time. Spacetime is a concept within the theory of relativity, an accepted scientific theory, that space and time are intertwined. Linking them together conforms to the theory of relativity while linking them separately does not because such linking implies space and time aren't intertwined.
Remsense's opinion: space and time. An implied technical inaccuracy is alright because the general reader would prefer to learn about space and time as separate concepts, even though these topics aren't technically separate.
@Remsense, feel free to provide your TLDR of this dispute if you want. Closetside (talk) 00:17, 28 June 2024 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20240628001700","author":"Closetside","type":"comment","level":1,"id":"c-Closetside-20240628001700-TLDR_for_3O","replies":[]}}-->
The current version seems much preferable to me. We know that the purpose of the first sentence is to introduce the topic to nonspecialist readers in plain English. We also know that lead links should not be required for the general reader to understand—it should be intelligible on sight. We have individual articles on space and time because they are not identical concepts. We also have the capability to explain that science considers space and time to be linked. The current version does everything asked of it, while the proposed changes introduces a much more abstract concept in the first sentence without adequately explaining it. ~~ AirshipJungleman29 (talk) 10:50, 28 June 2024 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20240628105000","author":"AirshipJungleman29","type":"comment","level":1,"id":"c-AirshipJungleman29-20240628105000-TLDR_for_3O","replies":[],"displayName":"~~ AirshipJungleman29"}}-->

Not quite on, both counts. There are many proper names normally used with the definite article in English running text, but those articles are not actually part of the name, e.g. Bible, United States. And no, not all proper names are capitalized in English, that's an oversimplification that works most of the time: other exceptions include summer, Remsense诉10:38, 5 July 2024 (UTC)[reply]__DTELLIPSISBUTTON__{"threadItem":{"timestamp":"20240705103800","author":"Remsense","type":"comment","level":2,"id":"c-Remsense-20240705103800-120.16.2.76-20240705100200","replies":["c-Chetvorno-20240706063600-Remsense-20240705103800","c-120.16.2.76-20240706083800-Remsense-20240705103800"]}}-->
