Assuming a perfectly rigid pole stretching from the Moon to the Earth. Wouldn't pushing on one end be felt instantly at the other?
If perfectly rigid poles exists, then yes information could be transmitted instantly. However, perfectly rigid bodies are forbidden by Special Relativity.wrekced said:Assuming a perfectly rigid pole stretching from the Moon to the Earth. Wouldn't pushing on one end be felt instantly at the other?

SR forbids perfectly rigid bodies precisely because it violates the postulate that information cannot be transmitted faster than the speed of light.wrekced said:Hmmm. Thanks! How in particular does Special Relativity forbid perfectly rigid bodies?

Information and matter are indeed two different things, but matter does move in this case. If you apply a force to a rod - it moves.Aethelwulf said:Information and matter are two different things. In a sense matter isn't moving anywhere. Its the communication between each particle?
