================================

  I can try to describe what should be the common sense difference.

  The Moon is about 1.3 light seconds (per speed of light 'c') from Earth as 
observed by an observer locally here on Earth. That is a Moon that is 1.3 
seconds backward in time regarding the Earth observer and a clock on Earth. 
The Moon that is relative to the observer on Earth. Except that the 
gravitational body of the Moon, the body that the Earth itself senses to 
exist in space and time, isn't there in that exact space where it is locally 
observed to be nor is it in that time -- where it is locally observed to 
be -- at all. In both space and time it has advanced in the Universe beyond 
the observed location during the 1.3 second difference in time. The Earth is 
gravitationally aware of the advance, being gravitationally aware of the 
exact gravitational location of the gravitational body of Moon, but the 
observer on Earth will not be aware unless he or she has perception and 
common sense enough to advance the physical reality of the Moon 1.3 seconds 
over its locally observed location in space and time.

  That isn't much of a difference between the local and the non-local, the 
more relative and the less relative, but differences grow, expand, with all 
increasing distance (including distance or difference in speed, distance or 
difference to the Planck horizon or universe, etc.) from any local observer.

  The distance or difference may become infinite. No observer is ever going 
to observe that infinity, that non-local infinity, but every local observer 
will locally observe, maybe even feel, the [locally] collapsed horizon of 
[non-local] infinity; or the locally collapsed horizons of such non-local 
infinities. No observer is ever going to observe the constant of infinity. 
Every observer will observe -- even work with -- some locally representative 
horizon, some local existance or being, of it.
