The Universe...upper case

How can the Earth be a proper noun, and the Moon, and the Solar System, but not the "Universe"...?

This, of course, is a logical non sequitur.

It reminds me of a cheeky critique of a photograph in "The Mechanical Bride" by Marshall McLuhan, which depicted advanced high school students standing behind a field of placards labeled with (something like) "The 100 Greatest Concepts in History". Which McLuhan perused, and added this aptly terse observation:

"War, but not Peace?"

Ditto Space.

'Space' is an upper case noun for a *place*, like the Earth, the Moon, and the Solar System, regardless that its dimension is undelimited: 'space' is a lower case noun for a specific (but generic) amount of it. Like a "workspace", or the space between these two brackets [ ]. You don't get "Lost in space". You're "Lost in Space"...irrespective of whether that's a TV show title or not. It wasn't the 'space Race' the US and Soviet Union waged against eachother.

How do we get this right? 2601:196:180:DC0:ADBF:1D31:A5F4:9ADA (talk) 12:11, 13 January 2025 (UTC)

:It's been discussed before [https://en.wikipedia.org/wiki/Wikipedia_talk:Manual_of_Style/Capital_letters/Archive_18 here], if you think it's wrong you can familiarize yourself with Wikipedia's policies and make a case, but you'll need to find some pretty serious sources that it's misspelled here, which may be an issue.

:Agree. It's been discussed ad infinitum on these pages. There is no consensus in astronomical literature whether to capitalize "universe" or not. However, I think it's clear "space" is a common noun. --Chetvorno^TALK 15:49, 13 January 2025 (UTC)

Temperature?

The highlight box indicates that the average temperature of the univers is 2.7 K. This surprised me. I know that the solar wind at 1AU has a temperature of millions of degrees, though the density is low so the heat content is low. Isambard Kingdom (talk) 01:04, 4 May 2025 (UTC)

:Are you surprised because it's high or because it's low? Remsense ‥ 论 01:06, 4 May 2025 (UTC)

:As the box notes, it's the temperature of the cosmic microwave background (and by extension the photons). The average temperature of the matter in the universe is much higher. Aseyhe (talk) 05:20, 4 May 2025 (UTC)
