#3 Light travels at 300 million metres per second, but sound travels at only 343 metres per second (through air). The light from any event which we witness taking place on the Sun, has taken 8 minutes 19 seconds to reach Earth. The sound of that same event would take 13 years, 11 months and 15 days to reach us, and that would assume that there is air between us and the Sun through which the sound could propagate, which there isn't, so it won't.
