Suppose you are in a spaceship traveling at twice the speed of light relative to the earth. Assuming that the Galilean transformation equations are true and the earth is approximately at rest relative to the ether, light from the ship's taillight will never reach the ship's bridge at its front end.

Question

Quizplus · Accepted Answer

The Galilean transformation equations are not true for speeds close to the speed of light. In fact, the speed of light is the same for all observers, regardless of their motion. This means that light from the ship's taillight will reach the ship's bridge at the same speed as it would if the ship were at rest.
