If air is blue how come a sunset, with LOTS of air, is red? I know the answer but it is the obvious next question with this explanation. [[Special:Contributions/162.158.74.171|162.158.74.171]] 17:22, 31 March 2017 (UTC)

:During the day the Sun heats the air. At sunset you see the result of this heating, the air glows red-hot or orange-hot and starts to quickly cool down.

Revision as of 23:40, 31 March 2017

I keep trying to correct the misspelled joung Girl to Young Girl but it keeps reverting. I corrected the two non-capitalized sentences and they stay put. Does "joung" have a meaning i don't understand? ExternalMonolog (talk) 14:55, 31 March 2017 (UTC)

There might be conflicting edits, that happens a lot with new comicsDontknow (talk) 15:34, 31 March 2017 (UTC)

Question - while I understand the intent of the comic is that overly complicated explanations can be confusing, isn't the title-text analogy incorrect? Doesn't chlorophyll scatter green light and absorbs other colors, whereas with the sky, it's really just different levels of scattering and very little absorbing (hence why a clear sky at dusk can appear red, the sky wasn't absorbing red light, it was just scattering it differently than blue light). Isn't that fundamentally different from the way most other common objects get their perceived color? (ps - I'm not a scientist, just curious, appreciate any feedback)

"Why are leaves green?" "Well, the leaf absorbs most of the colors, but not the green light, which it scatters instead." "Why is my shirt black?" "Well the cloth absorbs most of the colors, but just scatters the black light... wait..." Andyd273 (talk) 15:46, 31 March 2017 (UTC)

I like to think this is Miss Lenhart, continuing her science teaching in the same vein as in 'Venus'. There's no proof in the comic, but it fits nicely. Potentially something to add as a possibility in the explanation? 162.158.154.247 16:38, 31 March 2017 (UTC)

Yesssss <3 I had the exact same thought the first time Rayleigh scattering was explained to me: "isn't that just a specific mechanism of air being blue?" For some reason such explanations majorly tend to insist that the air is not in fact blue, and it has always bothered me. 162.158.111.19 16:41, 31 March 2017 (UTC)

Maybe the explanation should point out that the real reason the planes "stay up" is that the tiny birds are on the underside of the wings.--162.158.92.34 17:20, 31 March 2017 (UTC)

If air is blue how come a sunset, with LOTS of air, is red? I know the answer but it is the obvious next question with this explanation. 162.158.74.171 17:22, 31 March 2017 (UTC)

During the day the Sun heats the air. At sunset you see the result of this heating, the air glows red-hot or orange-hot and starts to quickly cool down. You can't see it glowing during the day because of the very bright Sun.--162.158.92.34 17:40, 31 March 2017 (UTC)
