Captain Ray, on the Galactic Explorer, sets off bright signal lights at the two ends of his spaceship so that they are seen as flashing simultaneously by General Kay, who is watch the ship go by. General Kay concludes that she was next to the midpoint of the ship at the instant when the lights flashed in her reference frame. This can only happen if Captain Ray, at the center of the Galactic Explorer: a. sees the lights flash simultaneously in his coordinate system.
b. sees the bow (front) light flash before the aft (rear) light.
c. sees the aft (rear) light flash before the bow(front light.
d. can calculate that the light flashes reach Corporal Maxwell so that the flash from the bow light reaches him before the flash from the aft light.
e. can calculate that the light flashes reach Corporal Maxwell so that the flash from the aft light reaches him before the flash from the bow light.
