Why is the sky blue? Really!?

Question

I want a scientifically based answer, not an opinionated one please.

SMART PEOPLE ONLY!

Answer 1

our atmosphere makes it blue. if we didn't have an atmosphere it would be black all the time. Something about reflecting and absorbing sunlight

Answer 2

B|C. It is. Case closed.

Answer 3

It's blue because the gases in the atmosphere (mainly oxygen and nitrogen, with a little water vapor and carbon dioxide and such) scatter and reflect blue light while absorbing red light. Light starts out coming from the sun, and if we had no atmosphere it would directly hit the ground, leaving the sky black and starry at all times. But the light rays bounce off gas molecules in the atmosphere, scattering the light in all directions and producing a diffuse blue glow throughout the atmosphere.

Hope this helps!

Answer 4

The sky is blue because there is particles in the sky that reflect a blue color from the suns light.  That is why the sky is not blue at night when the sun is on the other side of the world.

Answer 5

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.  

Answer 6

The sky is not blue; it only looks blue to us.

Answer 7

i got this off wikipedia:

The light from the sky is a result of the scattering of sunlight, which results in a light blue color perceived by the human eye. On a sunny day "Rayleigh Scattering" gives the sky a blue gradient — dark in the zenith, light near the horizon. Light that comes in from overhead encounters an air mass 1/38th of the mass that of a sunbeam coming along a horizon paths. So, fewer particles scatter the zenith sunbeam, and, therefore the light remains a darker blue.[
