A co-worker asked me a question this morning that has been bothering me all day. So, here it is. Numbers are rounded for conversation, asuming we're in a vacuum and no other outside forces. Lets say I create a straight 'Rod' with the length of 186,000 Miles long, lets also say this rod cannot be bent. If i push on one end of the 'Rod' how much time, if any, would pass before the other end moves? I agree with the person asking the question that information cannot be transmitted from point A to B faster than the speed of light. While other co-workers argue that the "Rod" is a single point in space that you are accelerating. I'm poor at explaining without drawing so maybe this helps Force applied-----> |A|-----------------------|B| (result?) Anyway, Its been bugging me. Could someone help?
