In the twin paradox example done in lecture, just before Alice arrives at the star (before she slows down), she observes Bob’s clock back where he is located. (In other words, she has a photo taken of his clock and her corresponding clock at that location, her clock being part of her lattice of clocks.) Compared to her clock, does she observe Bob’s clock to be behind, ahead, or the same time as hers?

Consider Bob on Space Station Omega. At time t = 0, Alice flies by in her spaceship at constant velocity, heading to the right. She then quickly reverses direction and heads back to the left, but stops and remains motionless (compared to Bob) before she reaches Bob’s position. Which diagram represents Alice’s world line in Bob’s frame of reference?

One way to synchronize a system of identical (and well-running) clocks is to use one master clock to set the other clocks, and then move the clocks to their various locations. What is a potential problem with this approach that was mentioned in the lecture?

Consider a train with three cars, moving to the right past Alice, who is on a train station platform. The front of the first car reaches Alice at time t = 0. In Alice’s frame of reference, which set of world lines represents the world lines of the three cars? (Let a world line represent the front of the car.)

Consider Bob on Space Station Omega in deep space. At time t = 0, both Alice and Kris fly by Bob heading to the right at the same velocity, with Alice in the lead. (Alice passes by Bob at t = 0, with Kris slightly behind her.) Which diagram represents the world lines of Alice and Kris in Bob’s frame of reference?
