I reported your post as being rude. I am interested in your reasoning and argumentation. There is no need to insult me instead of convincing me with evidence.
The sun sends out a wide-spectrum of radiation. Therefore direct sunlight would appear white in any gravitational situation because there are significant photons traveling at any wavelength, causing the observed "white shift."
The sky is not direct sunlight, it is the result of many photons be bent toward the observer, either by refraction or, as I am arguing, as a result of gravity.
If you could explain the specific logic of the sky being blue as a result of refraction (or refer me to a detailed online explanation), I would be interested.
You suggest it is stupid to question the explanation you have been taught, but have you considered that much stupidity involves taking insufficient explanations to be true, without thorough investigation of them?
From Wikipedia:
QUOTE
When light passes through our atmosphere, photons interact with it through scattering. If the light does not interact with the atmosphere, it is called direct radiation and is what you see if you were to look directly at the sun. Indirect radiation is light that has been scattered in the atmosphere. For example, on an overcast day when you can't see your shadow there is no direct radiation reaching you, it has all been scattered. As another example, due to a phenomenon called Rayleigh scattering, shorter (blue) wavelengths scatter more easily than longer (red) wavelengths. This is why the sky looks blue, you are seeing scattered blue light. This is also why sunsets are red. Because the sun is close to the horizon, the sun rays pass through more atmosphere than normal to reach your eye. Much of the blue light has been scattered out, leaving the red light in a sunset.
Basic basic research here. The sun doesn't have enough gravity to substantially "red shift" its radiation.

It was a rude response, but why not? The OP is obviously a troll: A truly stupid person wouldn't have the wit to present the snare, and the tone of the 'exposition' would have been more like an honest question.

That's the problem with trolls. They say they want to be 'convinced' when what they
mean is that they want to be argued with and debated over and fawned upon for their stunning brilliance...

I just reported your post as being rude, insulting, and adding nothing constructive to the discussion. I asked if you could be prohibited from posting, or at least put on probation.
That's freaking hilarious. No, you need to do a bare minimum of research before you go and ask other people to do the research for you. All you had to do was Google "Why is the sky blue" and you would have gotten millions of links, all with the same answer. Nothing makes me gag like complete and utter laziness.

what are you talking about? If you can't explain the basis for your knowledge, what's the point of putting it over someone else's? Posts should be enlightening in some way or other (i.e. constructive), not insulting to other people and degrading to their ideas.
I'm going to report your post as being insulting without making any constructive suggestions. Just putting people down like that is going to intimidate people out of posting on the forum.
You do that, please. When you do, also report that I told you to *** yourself.
The point of my post was to encourage you to learn to read, and at that, be able to manage high-school physics before you make
more of a fool of yourself.
Don't doubt that this message will appear in open forum, troll. As well as any epistles forthcoming from you.
Dolt. Troll. Idiot. Fool.

This is hopefully the last time I will bother responding to you, because it irritates me to do so. I suggest you avoid me too because we're just going to fight.
I googled this question but I think there is some value in integrating photogravitation into the issue. The problem with most of the physics I read is that it treats massive objects as if they were observable without regard for the fact that the light used to observe them has been influenced by their gravitation.
Why wouldn't this be true about the sun, Earth, moon, Mars, etc.?
Knowledge evolves. It's not the case that every new theory is wrong just because there is an existing theory already.
Good god. In case you haven't figured it out, I'm here for the LULZ. You are obviously providing the rare resource of LULZ to me, but I have to share, because your comments are just too precious to waste.
Of course gravitational redshift should be taken into account. It has been taken into account for longer than anyone here has been alive. Why would you assume that you have magically discovered something new when people have been ACTUALLY STUDYING these problems for hundreds of years.
