I was actually wander what would happen if you would just put a big rod of metal in 0 g and pushed it? If one end shifts 1 cm, how long would it take for the other end to also shift? Wouldn’t that be instant? Well, apparently the signal would travel at the speed of sound. Which is weird, right? It makes sense but it’s still weird.
