A spaceship is traveling directly towards a stationary asteroid with a speed equal to one-half of the speed of light as measured by someone on the asteroid.The spaceship turns on its headlights and the light is observed by the crew of the spaceship and by the person on the asteroid.Compare the speed of the light as observed by someone on the spaceship to the speed of the light as observed by someone on the asteroid.
A)The crew of the spaceship observes the light traveling faster.
B)The person on the asteroid observes the light traveling faster.
C)Everyone measures the speed of the light to be the same.

According to the principle of relativity, the speed of light is constant and independent of the motion of the observer. Therefore, both the crew of the spaceship and the person on the asteroid will measure the same speed of light. This is one of the fundamental principles of physics and has been experimentally verified many times.
