Why would'nt this work?
-
Wouldn't that still be normal light speed communication from earth to two places on the moon, not FTL communication between two places on the moon?
-
Reminds me of
- If you can have dinner with anyone, alive or dead, who would it be?
- No thanks, I've already eaten.
-
It was Alpha Phoenix

Objects like an unbreakable stick are still composed of atoms suspended in space and held together by the fundamental forces of nature. When you push on one end, the other end doesn't immediately move with it but rather the object experiences a wave of compression traveling through it. This wave of compression travels faster than we can perceive but still cannot travel faster than light.
Look up why arrows bend after they've been released by a bow, it's essentially the same mechanic.
-
Because you put the apostrophe in the wrong place?
-
It's still called the speed of sound. Your intuition is correct in that it's much higher for solid things, but it's still much slower than the speed of light.

Move a sheet up and down rapidly
You can see the wave travel across it
