What would happen if you had a lightyear long stick, and you pushed it. Would the other end move as you pushed it, or would it take a year?
In: Physics
so if you push it you think the other end would move immediately right but actually it would take time to get there like a whole year. the stick can only transmit the push at the speed of sound in the material so yeah you’d be waiting a while. kinda wild to think about how big the universe is and how slow stuff can be huh
