Consider Alice’s spaceship with the light pulse apparatus that shoots two light pulses toward clocks at opposite ends of her ship, each with speed c relative to the apparatus (as drawn in 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, and that c is greater than V. True or false: In Alice’s frame of reference, the two light pulses will hit the clocks simultaneously (i.e., each clock will read the same time when the light pulses hit).
