If you stand some distance away from the starter, you can see smoke comes from his gun before the sound reaches your ears.This great speed of light gives us some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light left the moon 1.3 seconds before it reached you.
