Okay.
So we’ve got an entirely flat surface that also happens to be the exact same length as the earth’s surface.
If you had one continuous piece of string that went from one end of that flat surface to the other, and on one end there was attached a bell… would you be able to ring the bell by pulling on the other end of string?
The speed of light is so much faster than the speed of sound, and that’s why sometimes you think someone is bright at first until you hear them talk.
