Revision as of 22:58, 31 May 2024
Dark matter in fiction was nominated for deletion. The discussion was closed on 11 December 2022 with a consensus to merge. Its contents were merged into Dark matter. The original page is now a redirect to this page. For the contribution history and old versions of the redirected article, please see its history; for its talk page, see here.
Dark matter was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

I reverted the edit as I said in the summary because the content is not "History" of Dark Matter. No historian has analyzed the history of Dark Matter and shown how primordial black holes became the alternative. On the contrary, the current consensus is cold dark matter: Lambda-CDM.
The sources and a summary are already in the article in the section "Alternative hypotheses". As it stands it appears to be WP:UNDUE: with in the section "Alternative hypotheses" primordial black hole is given an entire paragraph while other alternatives rate a couple of words.

Hypothetical form of matter that interacts with gravity, ...
getting cut off. Remember, the short description doesn't need to have as much detail as a lead sentence and is mostly used to disambiguate. Most people see the SD in the search bar, where they've typed in something that is similarly-titled, not similarly-themed.
I believe "Hypothetical form of matter" would scan quickly, as guidelines suggest, and disambiguate well enough from the other articles that have "dark matter" in the name, which are mostly works of fiction. The closest that might cause confusion is Dark matter halo, which has SD "Theoretical cosmic structure". But since you are engaged on this topic I will leave it to your judgement.

I think it needs to say more than that, but a little more briefly, such as "Hypothetical form of matter that interacts with gravity, but not with the electromagnetic field" Bubba73You talkin' to me?05:01, 31 May 2024 (UTC)[reply]
That's not a short description, that's a long description. SD's are not load-bearing in the way a scoping statement is, they're purely to lubricate searches. Wizmut (talk) 05:05, 31 May 2024 (UTC)[reply]
"Hypothetical form of matter" would be ambiguous, there's a lot of hypothetical forms of matter around (Exotic matter). If we need a very short description, then make it "Concept in cosmology" or something. Banedon (talk) 06:35, 31 May 2024 (UTC)[reply]
That works too. But the short description always appears alongside the title, and a user probably wouldn't be seeing the SD if they weren't already searching for something beginning with "Dark". Wizmut (talk) 06:54, 31 May 2024 (UTC)[reply]
Most people see the short description when doing searches in the search bar. In a search for "Dark" something, they want to know if each result they see is the one they're looking for. Is it a film, a book, a concept, a politician.
Think of something to search for up top in the search bar, type in the first few letters, and see how long it takes to tell if each result is the one you're trying to find. If it takes too long or doesn't make sense, it's probably because the SDs aren't clear and concise enough. Wizmut (talk) 08:53, 31 May 2024 (UTC)[reply]
But the next sentence says: "These descriptions appear in Wikipedia mobile and some desktop searches, and help users identify the desired article." They have no other purpose. They are invisible to normal readers. Johnjbarton (talk) 22:45, 31 May 2024 (UTC)[reply]
It also says "Short descriptions provide: a very brief (emphasis mine) indication of the field covered by the article" and later "More than 80% of short descriptions use fewer than 40 characters (including spaces)."
