   Special Relativity in absolute terms ..

   .. reveals what is transpiring behind the scenes of Einstein's treatment.

   Relativity Trail diagrams Einstein's clock sychronization in 
   absolute terms, explains the time-keeping differential, and ends all 
   confusion regarding relative frames of reference.  It's completely 
   compatible with Einstein's relativity, diagramming and explaining 
   it in absolute terms  -  eliminating the clock paradox and illuminating
   symmetrical assessments across inertial frames.
