Can you answer- Why is the sky blue?

I have found some interesting information on what causes the sky to be blue. Do you know of any scientific information relating to this?

it has to do with the atmospheare, and the fact gasses in it reflect blue. the color of water can vary, depending on how deep it is and on the color of the earth at it's bottom

The gases in the atmosphere colliding with neutrinos cause a chemical reaction in turn giving us varioius hues of color depending ont he time of day. Reds and oranges durring morning and dusk and blues and greens durring mean sun times. Water's color depends on the type of other chemicals and bacteris living in it along with temp. Much like gases only a more dense form of matter.

Had to add. The reds and oranges occur durring the earths rotation as side of the planet cools allowing all the particles in the atmosphere to also cool. This would also explains high and low currents in weather patterns. As the planet mantaines orbit slowly, depending on what part of the planet your on, you will see the horizon and the particles , once stricken by the sun reacts giving off the colors in the spectrum as the "first burn" occurs. Once it all settles we get blues and greens depending on smog and carbon dioxide in the air.

I was told it has something to do with the reflection of the sun off the water.

The blue light or wavelength is reflected more strongly than the red wavelengths.

I was told once that it had something to do with the atmosphere. It's some sort of chemical reaction, and so the "blue" water reflects off of the "blue" sky, and the "blue" sky reflects off of the "blue" water.

It does have something to do with the atmosphere and is more of the result of the gas particles that are hit by light waves which causes a new wave that scatters in all directions. The blue wavelengths are scattered towards earth and hince a blue sky.

The sky is blue due to the fact that sunlight enters the atmosphere and is reflected off the surface of the oceans. In other words, if the oceans were orange, the sky would be orange also. This is how it was explained to me by a science professor in college...

Then why is the sky blue and at sunset it is golden?

I don't know if he was right or not. I didn't really care. I got an 'A' in the class and got the credits toward my degree. That is all I cared about. I didn't really care about most of what we talked about. I just needed to pass the class.

Yeah the opposite effects occur when its night.

I think it has something to do the lights wavelength, blue has a shorter wavelength than the red color as the rainbow VIBGYOR. From the point of view of the observer the shortest distance to the light source sun is during noon and the farthest is during sunrise and sunset.

yes, there is some scientific basis behind this color of the sky. the water molecules present in the atmosphere are present in the form of miniature, sometimes microscopic droplets. when the sunlight falls on it, it has enough refractive index to refract this light onto the land. so as there is a change in the wavelength, what we predominantly see is the blue color. though sunlight is merger of seven colors, it is blue which gets maximally refracted. that is also why we see the rainbow after rains.
