+18 Special Relativity Changing Speed Of Light References. Web the speed of light in a vacuum is the same for all observers regardless of their relative motion or the motion of the source of the light. The special theory of relativity explains the unchangeable speed of light better than classical mechanics, but it also has some surprising consequences.
Rømer compared the apparent duration of io's orbits as earth moved towards jupiter (f to g) and as earth moved away from jupiter (l to k). Dr james o'donoghue edited by: (andreas zitlau /eyeem /getty images) albert einstein's theory of special relativity is an explanation of how a change in an object's speed affects measurements of its time, space, and mass.
