I have a thought/question that maybe someone with more knowledge than I could explain. From what I understand, nothing can travel faster than the speed of light, basically we cannot even communicate faster than the speed of light. So here is my question, imagine a hypothetical rod that is say X km long. For the sake of this argument I am going to assume there is no elasticity in this material. Now if I twist the rod at one end, the other end will twist instantaneously, presumably faster than light would take from one end to another. Now does this mean I am communicating information faster than the speed of light or am I missing something totally obvious.
