The Princeton experiment and others like it test the limits of the theory of relativity that Albert Einstein developed nearly a century ago. According to the special theory of relativity, the speed of particles of light in a vacuum, such as outer space, is the only absolute measurement in the universe. The speed of everything else â rockets or inchworms â is relative to the observer, Einstein and others explained.
