why are radomes white?
Most [radomes](_URL_0_) I have seen are white. Why white? White seems like the worst possible color choice because all the scratches and dirt will be obvious.

why do we feel such intense sensations after a part the body "falls asleep"?
I know that the "falling asleep" (I don't know what else to call it) part has to do with the restriction of blood flow to that part of the body, but once the blood starts to flow back normally, why/how does that cause our nerves to send these intense, almost unbearable sensations shooting through our body?

why time can move slower/faster dependant on where you are in space.
In the movie, Interstellar time moves at a much slower rate as they approach the black hole than it does back on earth. 1 hour there = 7 years on earth etc. Why is this? I know it is based on Einstein's theory of Relativity but I think I require an explanation for idiots.
