MY QUESTION IS IF THE "SHOT HEARD AROUND THE WORLD" COULD ACTUALLY TRAVEL AROUND THE WORLD, HOW LONG WOULD IT TAKE?(ASSUME THAT THE CIRCUMFERENCE OF THE EARTH IS 40,000KM)

Well, barring limitations in physics, wouldn't it be just the speed of sound making the distance? Keep in mind sound travels in a "spherical wave" so it will "catch up with itself" thus making it sooner than you think. Also, wasn't Krakatoa "heard around the world". If it was in Java, how long did it take for me to hear it?
