Last week’s episode on Einstein’s photon clock thought experiment:

Question #1: When the clock is moving towards you, do you observe its hands to be ticking slower, faster, or at the same rate compared to the rate of ticks that you observe when it’s moving away from you?

Question #2: When the clock is moving towards you do you see its hands ticking slower, faster, or at the same rate as a second clock that is stationary with respect to you?

Make sure you title your email: “Photon Clock Challenge Answer”

5 random winners will receive a PBS Space Time Digital Studios t-shirt!

Good luck!
