I'm a man who doesn't mind stating the obvious over and over again, because
so few see it or hold on it even when they do see it.

Light travels, rather it expands into, the universe always -- and I mean
always -- rear end of time forward in space / front end of time backward in
space.


For example: The Andromeda galaxy is about million light years away from
Sol. What we observe is a light time (-) record of a galaxy million
years B. C. E. relative to Earth C. E. or NOW (0)! SpaceTIME-wise it just
ain't there.

SpaceTIME-wise it is out in the "dark" universe because in spaceTIME it is
located that " million B. C. E." plus million future years -- that
"future" relative to Earth -- to its [NOW (0)!] location in space. We
observe it "rear-end (-) of time forward in space." "Front end of time
backward in space" is where it is in space-TIME (0), not where we observe it
to be in light-TIME (-). The difference is "future (+)" relative to the
Earth and the observer on Earth. That's from here (0) to there (0) in case
you aren't picking up on what I'm getting at. Cosmological constant 0| past
(-) via future (+) to present (0) (cosmological constant 0).

Once more though:

This is light's run in space regarding time: Andromeda BCE (-) (--) (---)
(----) (-----) (------) .... Milky Way CE (0).

Going the other way at the very same time: Milky Way BCE (-) (--) (---)
(----) (-----) (------) .... Andromeda CE (0).

So an observer in the Andromeda galaxy at a similar location to Earth
within the Milky Way sees the Milky Way -- and thus Earth -- to be
million BCE relative to his space-TIME CE NOW (0)! He (CE) sees the Milky
Way this way regarding time (as million BCE relative to his own "CE"
(0)) at the same time the Earth observer (CE) is seeing Andromeda the same
way regarding time (as billion BCE relative to his own "CE" (0)).

Each is on the mountain top of NOW (0)! looking down into the valley of
the PAST (-) of the other's galaxy. Neither can possibly [observe] the other
in this circumstance. Each observer (CE) is in the "dark" regarding the
other. And, as a traveler, would come from the "dark" to visit the other.
[Relatively speaking], would come from the relative "future" to visit the
other in the relative present (for the vast majority of the voyage).

But make no mistake about it, there is no violation of causality
involved -- that will occur. The [observation] is a matter of light-TIME
'relativity', not a matter of space-TIME 'reality'. That (the matter of
'reality') is strictly in the "dark" for the most part ("for the vast
majority of the voyage").

Once more: "Light travels, rather it expands into, the universe always --
and I mean always -- rear end (-) of time forward in space / front end (0)
of time backward in space." So take a wild guess which direction object
travelers will always travel all light paths. Remembering that no matter
what direction in space he will turn the nose end of, or the rear end of, or
side and side of, his vessel (0) into, he will turn it into an oncoming
light path (- (+ (0))), (- (+ (0)), (- (+ (0))), (- (+ (0))), ..... to
[always] travel nose end first a past (- (BCE)) via a future (+ (BCE)) to
whatever arrival in the present (0 (CE)). Side to side, and rear, will
always be a negative (BCE) to an even farther negative (BCE).

(shhh, whisper) Did I contradict myself? Don't look now but that last means
rear end 'rearward', he traveled into a past! even as nose end forward he
traveled into a future! to arrive in the present. And his rear end didn't
violate any causality in traveling into the past [back of him!]
