people are always trying to figure out why the sky is blue, why the ocean is blue, which was blue first, etc. well friends, apparently my books has got it all figured out.
"The sky is blue because more of the blue light than the red light from the sun is scattered toward the earth."
i guess that settles it, then....although the diagram they provide is actually an apple, not the sky or the sun, so maybe it's still a little questionable.
