Relativity of Simultaneity (クリ)
On the moon's surface, a passenger car is moving to the right. From the point at the center of ceiling, light rays are emitted at 45 degrees downward to the left and right. So, on the floor, there are two points of light. Position of two points are symmetrical for an observer in the car and stands on the moon's surface. This drawing should be understood by the emission theory.
