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

What of the observed traveler?, which is to say the trick of light, the
virtual traveler, always observed by the observer to be somewhere between
himself and the unobserved -- the unobservable -- real traveler in space but
always observed by the observer to be behind the unobserved real traveler in
time? Going away from the observer the unobservable real traveler always
pulls farther and farther ahead of the observer's observed trick of light,
the virtual traveler, in both space and time (the virtual traveler
[apparently] slowing down in time in falling farther and ever farther behind
the unobserved real traveler whose biology and clock and clock time is now
far advanced in time over what is being observed by the stay at home
observer.

The unobserved real-time traveler turning around to come home changes
nothing regarding the location of the observed trick of light virtual
traveler always located between him and the stay at home observer in space
and now observably -- by the stay at home observer -- far behind him in
time, thus appearing far younger in time, due to the original stretching out
of distance and c's unchanging constancy never accomodating the stretching
out (which is why the trick of light virtual traveler will always be between
observer and the unobservable real traveler in space, yet always slowed down
in time -- thus a history -- relative to both the real-time traveler and the
stay at home observer). But the unobserved real-time is now closing,
shortening or constricting in, in distance upon the stay at home observer
rather than opening, lengthening or stretching out, in distance. The light
he is putting out has a ever shortening distance to run, thus the trick of
light virtual traveler is no longer more distant from either the unobserved
real-time traveler or the stay at home observer. Though still between, with
all involved distances now closing, now contracting, the trick of light
virtual traveler is now closing in spatial distance, thus in appearance
rushing up in time -- no matter the direction -- to both the observer and
the unobserved real-time traveler propagating the light (light with an ever
shorter, an ever more contracting, distance in space and time to run).

This of course means the trick of light virtual traveler, the only
observed traveler, is getting ever closer in time and age to the real-time
traveler emitting the light for his only existence as the stay at home
observer's observed traveler. As the distance closes between the unobserved
real-time traveler and the observer, so does the history close as the
light-time-distance contracts. Light-time-distances and observable histories
/ times, in these cases, are one and the same thing.

Now only a fraction of a light second exists between the still
unobservable real-time traveler emitting light (and thus projecting the
time-line-historical image of himself as the trick of light virtual
traveler) and the observer who stayed at home. But still, within that
fraction of a light second expanse existing between reals -- within that
fraction of history still existing between reals -- resides that virtual
traveler in a space now only ever so slightly forward of the real traveler,
and a time, a history, now just ever so slightly behind the times of both
the unobserved real traveler and observer observing. At the observer the
real-time traveler catches up to (CATCHES UP TO) and merges with the virtual
in space. At the observer the trick of light virtual traveler catches up to
(CATCHES UP TO) and merges with the real-time traveler in time (having
closed up from a much more distant past in time than both the more recent
pasts of both the previously unobservable real-time traveler and stay at
home observer observing).

The virtual imaged traveler always positioned somewhere between the
unobserved -- and unobservable -- real traveler in space, thus always
observed to be somewhere, somewhat, closer in space to the observer than the
real will actually be (as the entire "observable universe" versus the entire
'unobservable universe' proves) will also be observed, whether going away or
coming on, to have a relative velocity slightly to greatly less than the
unobserved real's actual [relative] velocity by virtue -- or curse -- of
that observed closer [relative] positioning to the observer in space.

How much farther away, farther away in space, farther forward in time (+),
from the observer (0) is the unobserved, the unobservable, real-time
traveler (0) than the observed trick of lengthening, expanding, dimensions
of distance; trick of shortening, contracting, dimensions of distance; trick
of light and a light-time (thus histories') grid; trick of a UNIVERSAL
constant of c, imaged virtual traveler (-)?

And why is it that so many physicists make the trick traveler and clock,
the observed virtual traveler and clock, always one and the same with every
real-time traveler and clock (never splitting them up to form an expandable
/ contractible three corner dimensioned picture rather than just a two
point -single string- dimensioned picture)? Why is it that they always stop
at the observed, the relatively superficial, point / horizon and, like
implacable dark age priests, implacably demand that it be recognized to be
all there is or can be? Having the observation of one I can see, but why is
it that they also have the perceptiveness, too, of a strictly 1-dimensional
being? To wit, no perceptibility, no deeper layers of observability, at all.

Of course few of them are first tier thinkers and seers, nor even second
tier, nor even third tier, nor even fourth tier....
