   I am not sure, but since the coming of special relativity   
   there have been generalized spaces.  A view while in a space became   
   independent of sighting relative.  Viewing an object can not   
   determine one of these two cases.  But there is a universe view   
   allowed in these instances.   
      
   Think of the concept of a one dimensional horizon.  Space   
   at 90 degrees to the assumed motion vector becomes empty.  The   
   size of this empty determines fractional c speed.   
      
   But how do you know what is the proper forward?  If a rocket   
   engine caused the vector then a 90 degree view horizon is easy.   
   If you have no prior knowledge, the horizon angle is unknown.   
   But just using a 4pi search is allowed to check for it.   
      
   So you do get to know fractional speed. But not motion relative   
   to objects in the space.   
      
   This is a partial attempt to introduce world view implications.
