Factoid: No, it's because of Rayleigh scattering. Blue light is higher energy, so it scatters laterally across the sky. Other wavelengths of lower energy are pulled downwards by earth's gravity. That's why the sun appears yellow and the sky appears blue.

Earths gravity has a trivial effect on a photon of light.

I think he does not believe in what he posted, see the definition of factoid that he linked ...

 

[Rusty Shackleford]

Huh? Pls elaborate.

It retains the necessary combination of gases in sufficient density to scatter enough of the blue wavelength of light to appear blue.

This.

Rayleigh scattering is more prominent for shorter wavelengths, which is the reason the sky is blue (it's showing scattered light) and the sun is yellow/orange/red (the blues are scattered away, so the overall light coming directly in is yellow/orange/red, not white. The lower the sun is in the horizon, the more the Rayleigh scattering and the more orange/red the incoming light is.

It's just physics. If you know your physics.

"It puts the lotion on the skin"

When I said "elaborate", I meant "give a physical explanation which can be understood by high school or freshman level physics". I'm asking again.

My bad.
