CMB in the third paragraph should hyperlink to https://en.wikipedia.org/wiki/Cosmic_microwave_background 2A01:4C8:1562:EEC9:F93E:54AE:BCA1:70A9 (talk) 12:39, 19 February 2022 (UTC)[reply]

Cosmic microwave background is already linked in the first paragraph (with CMB in parentheses), and we have this guideline called MOS:REPEATLINK that discourages repeat linking. Praemonitus (talk) 14:20, 19 February 2022 (UTC)[reply]

Big Wave Theory

There is this recent theory called Big Wave Theory (many articles online) that is not contemplated on the Ultimate Fate of the Universe section of this article. Was it left out for some reason? — Preceding unsigned comment added by Luckylemming (talk • contribs) 17:15, 13 April 2022 (UTC)[reply]

I only see a few publications on the topic, so it might not have reached a sufficient threshold of notability yet. Plus the term "big wave" is used in other contexts. Praemonitus (talk) 15:53, 17 April 2022 (UTC)[reply]

It appears to be a proposal from over a decade ago [1] that had no discernible influence after a smattering of pop-science stories. That's far below the threshold for inclusion here. XOR'easter (talk) 18:56, 18 April 2022 (UTC)[reply]

"Big Bang Theory" listed at Redirects for discussion

An editor has identified a potential problem with the redirect Big Bang Theory and has thus listed it for discussion. This discussion will occur at Wikipedia:Redirects for discussion/Log/2022 May 6#Big Bang Theory until a consensus is reached, and readers of this page are welcome to contribute to the discussion.

Problems with the lead

I see some issues with the lead, which is supposed to be "introduction to the article and a summary of its most important contents". First, there is no mention of baryon asymmetry, which is why we're even here to talk about it. It talks about dark matter and dark energy, but never mentions that they are unexplained by the theory. In fact, I'm not clear why we need most of the third paragraph. Finally, it spends an entire paragraph talking about big bang vs. steady state theory, which actually forms a pretty minor part of the article. Hence, I think it needs a rewrite to better reflect the article content. Thanks. Praemonitus (talk) 02:33, 25 June 2022 (UTC)[reply]

Lead graphic conveys misleading expansion rate

The lead graphic is a misleading introductory visualisation of universe expansion. Please see my critique here; https://commons.wikimedia.org/w/index.php?title=File_talk:CMB_Timeline300_no_WMAP.jpg#Graphical_representation_of_the_expansion_of_the_universe Richardbrucebaxter (talk) 00:58, 7 September 2022 (UTC)[reply]

I suggest you take your concerns to NASA and see if they are willing to update the image. A modified version of that image would conflict with the WP:OR policy of Wikipedia. Praemonitus (talk) 12:41, 7 September 2022 (UTC)[reply]

Conflation of different hypotheses

With recent discoveries from the James Webb Telescope drawing attention to this topic, this Wikipedia article is apparently creating some confusion to readers conflating "Big Bang" with three different hypotheses: the initial singularity, the expanding universe, and a particular model for the expansion of the universe. One expert better describes this article's issues that need to be addressed: https://nautil.us/the-trouble-with-the-big-bang-238547. --MPerel 16:34, 12 September 2022 (UTC)[reply]
