Suggestion for addition of link

Hello, I noticed the first mention of the "FLRW model" does not link to an existing Wikipedia article that further expands on the first use of this acronym, and I believe that it would be a helpful addition for context. OverwhelmingOdds (talk) 00:01, 26 January 2024 (UTC)[reply]

Needs more sources

Every online source I have looked at says there's a lot of evidence disproving the other theories of the beginning of the universe or existence in totality. However, the Wikipedia article mentions only one, a book from 1996. Where are the rest of the sources? Galactiger (talk) 20:45, 26 January 2024 (UTC)[reply]

I've added a link to 'non-standard cosmology' in the 'See also' section. Praemonitus (talk) 01:03, 27 January 2024 (UTC)[reply]

Wiki Education assignment: English Composition 1102 085

This article was the subject of a Wiki Education Foundation-supported course assignment, between 4 March 2024 and 2 May 2024. Further details are available on the course page. Student editor(s): Jgleana (article contribs).

The article's intro is mistaken twice

(1) A theory and one of its elements, are quite different things. The cosmos' expansion, the Big Bang momemt, tP etc. are just elements of the theory !!!!! (2) The first formulations of the Big Bang Theory were written already in 1922 by Alexander Friedmann. based upon his own equations. So currently the article is also wrong regarding the first main step of the theory.

Therefore I suggest the following intro :

According to contemporary science, The Big Bang is the first moment of the universe. Its very existence, characteristics and the physical and cosmological processes that followed, are the main elements of a theory named The Big Bang Theory. Based on his own Friedmann equations, Alexander Friedmann contributed in 1922 the origin of the theory ...... יוסי ברנע בן פנינה (talk) 01:21, 6 May 2024 (UTC)[reply]

This makes sense to me. Ymblanter (talk) 12:37, 6 May 2024 (UTC)[reply]

Both Alexander Friedmann and George Lemaître proposed an expanding metric for the universe based on solutions to Einstein's theory of General Relativity. In 1928, Lemaître suggested that the universe may have originated at a single point -- a "primeval atom". Note that Hoyle's 1948 steady-state model allowed for an expanding universe with no big bang. Hence, I think that's why Lemaître gets credited. Praemonitus (talk) 13:38, 6 May 2024 (UTC)[reply]
