Theory of Relativity introduces several effects that need to be taken into account when dealing with precise time measurements. First, according to special relativity time passes differently for objects in relative motion. That is known as "kinetic" time dilation: in an inertial reference frame, the faster an object moves, the slower its time appears to pass (as measured by the frame's clocks). Gene… WebGPS systems, for example, rely on the precise measurements of time and space that are made possible by the theory of relativity. In addition, the study of relativity has inspired new avenues of research in fields such as quantum mechanics and string theory, which may hold the key to unlocking even more secrets of the universe.
