Why is the SKY blue?
it is because red light is faster than blue light and we can't see the red light because it is too fast for us so we only see the red light. when the sun sets, the light slows down, so that we can see the red light and the blue light slows down so much that it never even gets here until the next day and we then see it with all the other blue light in the sky in the morning .....
