Why is the sky blue.?
Because God made that way.
Cause it feels like being blue:)
It's not its black it looks blue cause the sun is reflecting off of the ocean
light is made up of all colors of the spectrum. particles in the atmospere absorb all colors of light except what you actually see. the sky changes color as the sun is closer to the horizon because the light is passing thru more partcles
BECAUSE IT lS
Maybe it's sad.
Light is refracted through the atmosphere, causing all the colors we see. Lots of info on this on the internet. I can't explain it well.
Because Aliens Don't Wear Hats
Well giant narwhal start fighting and explosions are everywhere and then turn the sky blue. :)
