I find it weird that so much professional study still refers to an assumed "cosmological constant", when it is observably ''not'' constant. Feels like we should be calling it "the cosmological value", since expansion has not been occurring uniformly & considerable localized variation in "vacuum energy" seems relatively certain. Parts of the observable universe are considerably older than the "big bang" that so much theory is hung upon; what part of "these laws are localized effects, not unchanging constants" has ''not'' been obvious, for >30 years?

When I added the transcript it broke the "Created by a BOT" tag on explanation, even though I didn't touch explanation 172.71.151.98 05:30, 18 April 2023 (UTC)

No, it was broken before your edit. Someone else changed "BOT" to "Z=90s KID". The equal sign causes problems for mediawiki, but it's been fixed now. --Orion205 (talk) 06:03, 18 April 2023 (UTC)
For anyone who would benefit from a deeper explanation:
In the syntax for templates, equals signs come after parameter names (see Help:Templates § Parameters). So, Created by a Z was parsed as the name of a nonexistent template parameter, and 90s KID - Please change this comment when editing this page. Do NOT delete this tag too soon. was passed in as that parameter's value.
That still wouldn't necessarily be a problem. It just also left the first parameter empty. This specific template is programmed to show an error message when that happens. ~AgentMuffin 06:13, 18 April 2023 (UTC)

Two times the red tint around Megan has been mentioned, in explanation and transcript... I cannot see that, no matter how much I zoon in. Is it actually there (can it be measured on the image file?) or is it just someone who wished it was like that? If it can be measrued it should be explained and if not then the mention should be deleted --Kynde (talk) 07:13, 18 April 2023 (UTC)

What I meant was that Megan's line art in this comic appeared more brownish/reddish to me than the line art of the other characters. Specifically, the colour hex #472425 using an online colour hex checker. --Multiuniverse (talk) 07:22, 18 April 2023 (UTC)
It's definitely there, but I didn't notice it until I saw it mentioned. It's subtle enough that I imagine certain displays or differences in individual color perception could make it harder to see, but trust me, it's certainly there. 162.158.222.5 07:24, 18 April 2023 (UTC)
Why is everyone so unsure? it's definitely there. Mushrooms (talk) 09:00, 18 April 2023 (UTC)
Not all monitors have the same quality, I can imagine that on some cheapish laptop screens it can be a lot harder to see -- 172.71.131.134 12:20, 18 April 2023 (UTC)
On this laptop (Dell Latitude 600 - good for its time, a rather archaic thing now) it shows just. Took the explanation mentioning it for me to notice. (And, yes, I'm using pretty archaic kit, at this moment. Though not my oldest, because I tend not to throw away 'perfectly working' things. That said, when it comes to remembering how the universe is, I'm not quite in the "I remember when all this was fields" category...) 172.71.242.203 19:31, 18 April 2023 (UTC)

Before anyone embarrasses themself by asking, "multimanteau" is obviously a portmanteau of "multiple" and "portmanteau". Sheesh, get with the neurolinguistic program. "Phrasemanteau" would also be an acceptable neologism. - Frankie (talk) 11:48, 18 April 2023 (UTC)

Inconstant "Constant"

I find it weird that so much professional study still refers to an assumed "cosmological constant", when it is observably not constant. Feels like we should be calling it "the cosmological value", since expansion has not been occurring uniformly & considerable localized variation in "vacuum energy" seems relatively certain. Parts of the observable universe are considerably older than the "big bang" that so much theory is hung upon; what part of "these laws are localized effects, not unchanging constants" has not been obvious, for >30 years?

This may be related to the fact that there are so many actual problems around the cosmological "constant" that noone wants to bother renaming it before getting better idea what it actually is. -- Hkmaly (talk) 21:01, 18 April 2023 (UTC)
