Let's get a better mental model beyond just "because blue light scatters more". I stream science LIVE M-W-F 1pm PT.
Here is Sally's channel!! She is live streaming a series on evolutionary biology-
BOSE will be sending out 8 pairs of their dope 700 headphones. 4 will go to people who post about our class on Insta, Twitter, FB or TikTok. 4 will go to my favorite challenge responses or answers to questions. You can post your challenges by tagging me on any social media platform.

But red has less frequency, so red should loss its all energy and we should see the blue sky, I am confused...

The sky is blue based on wave length... is Mars sky so red? I doubt it. Pictures doctored? Probably. I've been teaching this to my kids for years. Wavelength of light

@Dying Energy Exactly. Their "proof" has been disected, torn to shreds, and proven false so bad that they wiped the mainstream internet clean of the topic and even removed all related educational content on YT in 2017 and replaced them all with joke/prank videos. Very strange move for something labeled as a silly conspiracy theory. I mean why not also remove all the UFO, bigfoot, and lochness monster videos too right?

Also the firmament above holds back the waters. Meaning what weve been told is space is actually water and nobody is going there.

In order to see the reds well, make sure you use an old incandescent flashlight. If you use a modern LED flashlight, pick one with a high CRI and R9 value.
