if we're in a cave why is the sky blue?

[Saphire]

The crystal then extends up to the surface of the cold earth above, where the sun shines on the crystal f the surface which then relfects the light down through the Azure crystal and into the cave.

Only problem with that diagram is how the HELL is the sky blue when there\'s clearly no way a sky could possibly be contained within... then again, there isn\'t a distance referance so we really dont now the distance between the highest leven and the crystal/ceiling.

Right, I think its just one of those things we need to accept...

[snow_RAveN]

i guess the reason for the blue sky is cause of the crystal dont seem to be any logical explanation other than that ... maby its they way light travels ya know blue or is it purple being the faster colours with more penetrating power ? it explaines why the sea is blue .... (ok so its a little green in some parts but thats cause of agle )

[Levski]

Ah, ok, thanks Icefalcon for clearing it up

Dont take it to nerd level!! No one really cares! Just play the game and DONT try to make reality out of everything in the game.... its fantasy! Use your imagination... perhaps the atmosphere itself is different from ours and thats why it shows up blue.  What do you want from me a poem???!!

I\'m going to take it to a nerd level...So there.

The Reason the Sky is Blue

Light is made up of electromagnetic waves.

The distance between 2 crests in this wave is called the wavelength.

White light contains all the colors of the rainbow.

The amount of light scattered for any given colour depends on the wavelength of that colour.

All the colors in white light have different wavelengths.

Red light has the longest wavelength.

The wavelength of blue light is about half that of red light.

This difference in wavelength causes blue light to be scattered nearly ten times more than red light. Lord Rayleigh studied this phenomena in detail. It is caused the Tyndall effect or Rayleigh scattering.

Lord Rayleigh also calculated that even without smoke and dust in the atmosphere, the oxygen and nitrogen molecules would still cause the sky to appear blue because of scattering.

When blue light waves try to go straight through an oxygen and nitrogen molecules, its light is scattered in all directions because of this collision.

This scattered blue light is what makes the sky blue.

All other colors (with longer wavelengths than blue light) are scattered too.

Blue light\'s short wavelength causes it to be scattered the most.

(The shorther the wavelength of the color, the more that color gets scattered by the atmosphere)

Actually, violet has the shortest wavelength of all colors. Violet is scattered even more than blue light. However, our eyes are much more sensitive to see blue than violet, therefore we see the sky as blue.

Very little visible light is absorbed by the atmosphere.

The same would happen in Yliakum. I\'d imagine the distance between the Azure Sun and the people looking up at the sky is great enough to make the thing appear blue.

There you go. An explenation.

P.S. If you look to the sides of the sky dome you can see grey cracks which look like the cave\'s walls.
