You are racing away from Earth in a super spaceship in which you can continually increase your speed.Which of the following best explains how people on Earth will perceive your speed?
A)They will know you are going very fast but will have no way of knowing whether you ever exceed the speed of light.
B)You will see any beam of light from Earth coming toward you at the speed of light,which means it will catch you.Thus,the people on Earth must conclude that you are going slower than the speed of light.
C)An imaginary spaceship can go as fast as it wants,so the folks on Earth soon will see you going faster than the speed of light.
D)You may soon be racing away from Earth faster than the speed of light,but,if so,people on Earth will no longer be able to see you.
E)Without more information,it is impossible to know how fast you would see a light beam from Earth coming toward you.If it happens that you are going fast enough so that the light can't catch you,then people on Earth would find you to be going faster than light.

According to the principles of relativity, the speed of light in a vacuum is the same for all observers, regardless of their relative motion. Therefore, even if you are moving away from Earth at a high speed, a beam of light from Earth will still approach you at the speed of light. This implies you cannot exceed the speed of light from the perspective of observers on Earth.
