Q:
Hi, Great initiative, this! I have a question about a trans-galactical typewriter. If you move a solid object, all parts of it move with the same speed/acceleration. So if I do a thought experiment, and take a very, very long metal rod and I move it at one end one cm forward, the other end will move one cm forward at the same time. So, let me now connect the hammers of an old-fashioned typewriter here on Earth with a similar typewriter on Mars. Would the not my message arrive instantly on Mars, about 12 minutes before the video recording of me typing arrives on Mars? If the end of a rod does not move in the same way as the beginning that I'm moving - how much is then the difference? Would one be able to do a real live experiment here on Earth to measure the difference (with the speed of light?)
