Traveling Twin Paradox: Covariance of Space and Time

Authors: John A. Gowan

Moving clocks measure spacetime, not just "pure" time. Insofar as the intrinsic motion of light and the intrinsic motion of time are the entropy drives of free and bound energy, clocks also measure the march of temporal entropy. A moving clock incorporates space into its time measurements, thus "spacing out" its ticks or temporal intervals in relativistic proportion to its velocity, hence "running slow" (and hence measuring spacetime, not just time). The stationary clock of course does not incorporate any space into its temporal measurement, and so records "pure" time. A clock's running rate can be changed by mechanical accelerations/decelerations or a gravitational field. This was Einstein's great discovery regarding the relative or local nature of time.
