Why a round trip slows a system's evolution (Introduction, Part 2 video)

In the qm view, the changes in rates of clocks and all other processes specified by the physical change ratio, rv, (explained in the Introduction, Part 1 video) exactly account for the "relativistic" clock slowing predicted by relativity theory and observed in experiments.  The qm  view explains why a clock that makes a round trip ages less than a clock at rest where the trip begins and ends.

Relativity theory indicates that the slowing of the traveling clock is due to the relative motion between the clocks.  This explanation for the clock slowing results in the long-perplexing Twins or Clocks Paradox.  The qm view shows that the physical causes of the observed clock slowing are not as simple as relative motion, and that the paradox is the result of not understanding the causes.
