Einstein's principled account began with the postulate that the laws of science should appear the same to all freely moving observers. In particular, all observers should mea sure the speed of light as the same regardless of how fast they are moving. Thus, there is no "universal time" that all clocks measure; rather, everyone has his or her own personal time. If one person is moving with respect to another, their clocks will not agree.
