This is a very simple question, which is why I am probably having a hard time finding the answer. Why is light not visible when it travels. You see the light of the sun, but you don't see the light travel to your eye. Light does not appear unitil is hits something, right? So the sun gives off light, the light then vanishes, travels in darkness, then appears again when it hits something or it is observed. Why?
