Imagine that you had a spaceship that could travel at the speed of light. If you got in your spaceship and took a well-running clock (any clock that keeps time well) with you, and then passed by the Earth going at the speed of light, what would you observe about your clock?

Your clock would run slower than normal.

Your clock would run faster than normal.

Your clock would keep time as normal.

Your clock would be frozen (stop running).

Let Bob have a spaceship with a clock at each end, both of which are synchronized in his frame of reference. Alice has an identical spaceship with a clock at each end, both of which are synchronized in her frame of reference. Her spaceship is docked at the local spaceport, with the front end pointed to the right (positive x direction). Meanwhile, Bob flies by in his ship at a speed V heading to the right (positive x direction). Alice observes Bob’s clocks as he flies by. What does she observe, according to her frame of reference (and lattice of synchronized clocks)? (Tip: Sometimes it helps to draw a picture to visualize what’s going on.)

In the “pole in the barn” example done in lecture, how can Bob observe/photograph the front of the pole to be located at the rear door of the barn at 44.4 nanoseconds and the rear of the pole to be located at the front door of the barn at 44.4 nanoseconds (so the entire pole is in the barn), while Alice agrees with Bob’s clock readings but never herself observes the pole to be entirely within the barn?
