When I was about 14 there was supposed to be a meteor shower and my family went out to into the country to watch it. It was beautiful and wonderful, until one of the meteors made a noise. Exactly the sort of noise you would expect a shooting star to make, starting when it appeared and stopping when it fizzled. No one else thought this was strange, but I was intensely confused: how could we hear a meteor? It's so far away! And perfectly synchronized? Even airplanes are far enough away that their visual and auditory positions don't match.
