   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
   illuminates symmetrical assessments across inertial frames.
   
   It's completely consistent with Einstein's relativity,
   diagramming and explaining it in absolute terms.

   The clock paradox (twins paradox) of special relativity 
   cannot be resolved without acknowledging an actual
   hierarchy of clock rates dependent on an actual hierarchy
   of inertial motion.  And this we do in Relativity Trail.






     Relativity Trail can be purchased, for now, at the U of M campus bookstore.
     I manufacture the books myself in small quantities.  When I decide to quit making
     such physical copies of the book, I'll post the pdf file of the book for free download.

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.
