The sky is blue, definately blue.

As opposed to.......?

To other colors it could have been?

wow I agree 100%

it is here right now...stunningly so.

I agree....from where I sit, it can be blue.

what causes that?

What if you were color blind? Would the sky still be blue?

It's the reflection from the atomosphere that casues the blue.

From some random website

WHY IS THE SKY BLUE?

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.

The sky appears blue to us on a clear day, because the atoms of nitrogen and oxygen in the atmosphere separate the suns white light into its many colors, and scatter them throughout the atmosphere.

The wavelength of the blue light scatters better than the rest, predominates over the other colors in the light spectrum, and makes the sky appear blue to us.

The scientific name for this phenomenon is the Tyndall effect, more commonly known as Rayleigh scattering.

This phenomenon describes the way in which light physically scatters when it passes through particles in the earths atmosphere that are 1/10th in diameter of the color of the light. The light spectrum ranges in wavelength from red to violet, and, since the wavelength of the blue light passes through the particles with greater ease than the wavelengths of the other colors of light, the sky appear blue to the naked eye.

The human eye has three types of light receptors, known as cones, located in the retina. The cones are either considered to be red, or blue, or green, based upon their strong response to light at these wavelengths. As light stimulates these receptors, our vision translates the signals into the colors we see.

When gazing at the sky, the red cones respond to the small amounts of red light scattered, and even less strongly to the orange and yellow wavelengths. Although green cones respond to yellow, their response to scattered green and green-blue wavelengths is stronger. Finally, colors near the strongly scattered blue wavelengths stimulate the blue receptors.

In short, the skylight stimulates the red and green cones almost equally, while stimulating the blue cones more strongly. For these reasons, our vision naturally adjusts as clearly as possible to separate colors.

And they didn't think I loved science......boooo shwaaaaa

one time on acid..the sky was all kids of crazy colors

I can't believe we don't have anyone here disputing the color of the sky.

But where's the god stuff?

Color is a good metaphor for truth.

he made the sky lee.please keep up.

I need to put my runners on and leave the masturbating for peace thread alone...

I keep getting distracted Jax..

Well, if you insist,....

I was just outside. The sky here is pitch black and there's water falling from it.

the masturbating for peace thread

I'll be back

I knew it.......but during the day is it blue abra? or is it something else all together?

Hey!!!

MINE'S BLACK, TOO!!!

NO WATER FALLING OUT. MINE'S NOT LEAKING, HERE!!

but there are little white dots that flicker in mine.


???????????????????????????????????????????????
