Why is the sky blue?
« on: 31/05/2023 03:58:43 »
Why is the sky blue? Anyone will tell you about the atmosphere 'scattering' light, I propose this for arguement.
The light of a star red shifts and blue shifts in accordance with its movement towards or away from you. If you compare the effects of momentum on an object to the effect of a gravity field, then the light entering a gravity field would blue shift and hence the sky is blue!

Scattering also accounts for the direction of the light as well as the spectrum and the red sunrise/sunset.
Your idea doesn't.

I have noticed with posters like you, that when there is an explanation for a phenomenom that has been demonstrated countless times, you always go off and try to propose a different, far more complex explanation. I suspect that this is because you do not find a rational explanation 'exciting' enough and try to shoehorn some nonsense that you perceive as being a lot more exotic and sexy. It merely displays your lack of understanding about science and opens you up to justified ridicule. Why do it?

Could be that, but I think they just don't understand the real explanations and why they are better.

The light emitted by the Sun is red shifted by the Sun's gravitational field by a significantly larger factor than the Earth's gravitational field blue shifts it because the Sun is much more massive than the Earth. Despite this, the Sun's light still appears white from space. The degree of change in wavelength is incredibly small.

Besides, what Bored Chemist said about the sky being red at sunset also demonstrates that gravitational blue shift cannot be the reason behind the sky's color: the Earth's gravity doesn't change at sunset.

Of course it does, otherwise the sun wouldn't rise again the next day. Heliocentrism is a conspiracy against the Pope.

Uhm, the light that hits the earth sideways at sunset makes the sky red and blue and all colors between. Also the moon on the horizon appears bigger because of the amount of atmosphere acting as a lens to magnify it. Could the colors of the sunset have to do with more atmospheric lensing?

No It doesn't.
The sunset is not like a rainbow.

You seem not to have noticed; you get red and blue, but you don't get yellow orange and green.

Do you really not understand that, because your idea predicts things  the we do not see, your idea is wrong?

Could be that the sun is wrong and more colors would be appropriate, making you wrong,wrong again, making the sun mad.
Anyhoo when light falls into the gravity field of the nucleus, it presumably blue shifts going in and red shifts going out.
The speed of light is thought to be a result of the background temperature of the aether. But as light cools off it continues at the same speed? why is that bored chemist?

If sunlight were to be blue shifted by the earth's gravity then the bulk of sunlight would also be blue, not just the sky.

Quick answer; Maxwell's equations.

This is exactly the kind of spam that got you banned the last time. If I observe that you haven't really changed your ways, you'll get banned again. Please act more maturely when other members disagree with you.

The gravity of a single atomic nucleus would be so incredibly tiny that I don't think red shift and blue shift would even be detectable with our best instruments.

Can you give a citation for this?

Light doesn't have a temperature. Temperature is a quantity of bulk systems such as a collection of atoms.

So the sunset is red shift and blue shift combined. It's probably because the sun is shining sideways through the gravity field of earth. I suspect, and haven't seen a sunset lately to check, but that the sun has to be setting behind the horizon before it begins to show red shift. It gets bigger because of lensing of  the atmosphere, but when it sets behind the horizon, it would create redshift because with the portion of the sun that is hiding?

No, it is just an atmospheric effect.
