From time to time I like to chat with flat Earthers and help them clear up their confusion. Today I came upon a question I couldn't answer, and since it is summer, I couldn't ask a professor. Would two people, on two separate planets, holding one pole, feel a push from the other instantaneously without violating the speed of light? I realize the answer is in the elasticity of the material, but what if the material was rigid? This might be an easy question to answer, but I am at the beginning of my studies.
