   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 consistent with Einstein's relativity,
   diagramming and explaining it in absolute terms  -  
   eliminating the clock paradox and illuminating 
   symmetrical assessments across inertial frames.

     Relativity Trail was given a special place of honor at the Science Museum of Minnesota Bookstore,
     front and center on their front table, greeting visitors as they walked through the front door.

In a few words..

The absolute approach to
relativity reveals the same
thing that the relative
approach assumes -- that
there is no privileged
frame of reference in which
to conduct experiments.
Thus, the absolutist and
the relativist agree that
one cannot detect one's
motion status relative to
the universe using electro-
magnetic experimentation.

It is meaningless to ascribe
linear or rotational motion
to the whole of the universe,
considering that the universe
has nothing to push off 
against. It is the baseline 
for the motion of its 
constituent parts.
