Here is a question I posed to my Facebook friends this morning while waiting on my ride to work. I thought about the answer to it myself and got a good brain workout from it! I would like to know your thoughts: You have a rigid pole that cannot bend or stretch or otherwise deform in any way. The pole is exactly one light year in length. You pull on one end of the pole and it moves one meter. Does the other end move the same distance at the same time? Why or why not?
