If you were traveling at the speed of light, next to a beam of light, the beam would appear to
1) be at relative rest, traveling beside you at an equal speed.
2) still travel away from you, but at a speed less than c.
3) travel away from you at c.
From this we see that the speed of light in free space will be found to
4) have the same value for all observers.
5) be relative to the motion of the observer.
Answer: 3, 4
