They sky is blue due to the effect of the atmosphere on the light from the sun. It disperses it (or something like that), which gives it that blue colour. At night, as the sun is not shining, it is black.
Dunno why rap was invendted. Just guess someone thought talking to music in an odd way would work out. BTW has anyone seen videos of William Shatner 'singing'. All he does is speak to music, and not in a way that fits either. And the Ballad Of Bilbo BAggins by Lenord Nimoy (Spock) it also funny.
