imagine you have this hugely long rod. like a lightyear long. and theres a button on one side of the rod. you, on the other side, push the rod onto the button (as fast/s;pw as you want), conveying a signal to the other side, and basically sending information faster than light. whats wrong with this picture? (i dont know) also, if that works, than you dont need a physical rod, you can go with something else, electron, particle etc. anyone know?
