Time flies.  Been one year since I had the
honor of playing host for one month to 
Scott Booth -- talented folk songwriter
and singer.  Four albums to date.  
Played lots of catch with the baseball 
and rode bikes.  Also had the honor of 
creating Scott's official website for 
his music.

Listen to my favorites at his website:

Your host,

The preprint for my relativity journal article is at:

Relativity in absolute terms

There are only three sane sections in the Wikipedia article 
on the twin paradox of special relativity.  I authored those 
sections in 2011, and they've been there continuously since that time:

Here's the link to the three sections below.

   4.  A non space-time approach
   5.  The equivalence of biological aging and clock time-keeping
   12. No twin paradox in an absolute frame of reference


On several fundamental levels, Relativity Trail eclipses the works of Poincare, Lorentz and Einstein regarding the underpinnings and kinematics of special relativity: link: The originality and uniqueness of Relativity Trail
The twin paradox of special relativity cannot be resolved without acknowledging a hierarchy of clock rates dependent on a hierarchy of inertial motion. © 2022 relativitytrail.com Relativity Trail explains the time differential between reunited clocks, eliminates the twin paradox, diagrams Einstein's clock sychronization in absolute terms, and ends all confusion regarding relative frames of reference. It's completely compatible with, and in fact subsumes, Einstein's relativity. It reveals what is transpiring behind the scenes of Einstein's treatment. Spacetime is shown to be dependent on Einstein's clock synchronization method, and is properly relegated to a geometrical construct which comes up short as a physical reality. © 2008 relativitytrail.com Relativity Trail, with 192 pages, 65 diagrams and 75 illustrations, will provide you with complete detailed algebraic derivations of all the kinematical effects of special relativity. Everything is charted out in absolute terms against a system at rest with respect to the totality of the universe for perfect clarity as well as soundness of theoretical basis. It is the totality of the universe that imparts the inertial properties of clock rates and lengths which generate the effects of relativity. This is explained in detail in Relativity Trail Introductory document: Relativity in absolute terms (can be read with comprehension in twelve minutes) Absolute versions of Einstein's postulates (a snippet from the above document -- can be read with comprehension in three minutes) Twin Paradox Animation on youtube. Light rays and traveling twins are charted in absolute terms, free of the misleading space-time diagram. I wrote the program code for the animation using QuickBASIC for DOS. Updated 02/15/2024
