This from Eric:
Eric: "Mom, you know how on cartoons, going faster than light is always depicted as, like, a swirl of colors? Well, I think I should be all be all black, because you are outrunning the light. If you turn a flashlight on while you are going at light speed, it's like dropping pennies behind you while you are skydiving."
Me: "How's that?"
Eric: "Oh, because the maximum airspeed velocity of a penny is much slower than that of a human."
