Consider a situation that is similar to that in one of the video lectures, i.e., Alice observing Bob traveling from Earth to a star at a certain distance from Earth. Assume that the Lorentz factor for the relative velocity between Alice’s frame of reference (the Earth-star frame of reference) and Bob’s frame of reference (the spaceship frame of reference) has a value of 2. Alice, using her system of clocks, measures the elapsed time it takes Bob to reach the star as 8 years. She also takes a photo of Bob’s clock as he passes the star. According to the photo, how much time has elapsed on Bob’s clock from when he passed by Earth?

Consider Alice’s spaceship with the paintball apparatus that shoots two paintballs toward clocks at opposite ends of her ship, each with speed S relative to the apparatus (similar to the video lecture). Assume that Alice has properly synchronized her clocks, that her spaceship is moving with speed V to the right (in the positive x direction) relative to Bob, that S is greater than V, and that S and V are much less than the speed of light. True or false: In Bob’s frame of reference, the two paintballs will hit Alice’s clocks simultaneously.
