   As a "foil" in this experiment class, I use the concept of simultaneous.   
   An event in both reference frames can be considered happening at   
   the same time by act of event.  Except here the event is a pole on   
   the spaceship hitting a pole a planet.  The destruction of the poles   
   are then the triggers for a measurement. Validating this class.   
      
   Now how infer relative ages abstractly? My intuition is a simple   
   concept exists that is obvious after the fact.
