Say we have this scenario, we have two bodies (big rocks, asteroid etc), existing in the vacuum of space, both are in perfect sync with each other (distance between them remains static) and are 1 light second apart in distance. Bob is standing on one rock and Mary on the other. Each has a radio, but there is also a long rod made of some material we haven't discovered yet that does not bend, stretch or compress when stress is put on it. Both Bob and Mary are hanging on to one end of the rod. Bob says "hi Mary" at the exact same time he pushes on the rod. Will Mary feel the pressure on the rod at her end before she hears Bob say "hi"?
