This is the best place for me to go over the constant of t=0 (little 't') once more, though I've covered it in a few posts before.
Einstein dealt in "past-future" without any mention of "now'." That I know of, and his best friend Kurt Godel certainly knew of by what he described of time, Einstein never denied the existence of "now", just never alluding to the existence of it, either.
Now, I've reached an understanding, to my satisfaction in my modeling, of how the train works. It does not work past (-) --> present (?) --> future (+)! It works past (-) --> future (+) --> now (t=0)!
Actually, and better yet, pasts (-) --> futures (+)--> now (t=0)! Einstein's soft rendering of time, past (-) - future (+), is maintained soft, but now (t=0) is universal quantum entangled hard constant. and tied to the Big T=0 of the Planck Big Bang (E) collapsed Horizon. . . . and to Big Crunch (M) / Big Vacuum (C^2).
All travelers, particles, ships, planets, solar systems, galaxies, you name it, are always in motion and / or animation. Everything unobservably real of every paralleling universe (u), the make up of every paralleling universe (u), which, thus, includes the cauldrons of the universes -- in whole --themselves, is in motion and / or animation. Universally in motion to -- universally traveling time and / or space-time to -- the universally hard constant of now (t=0). . . always connected to the constant of the Big Time and / or Timelessness of the Planck Big Bang (E) collapsed Horizon and . . . . (the Horizon Universe (U) never to be reached nor even approached, and never to be left behind either -- always maintaining its Horizon, its place, as constant horizon (C = 300,000kps = 0 (the Universe's 0-point. . . . And by the way, the Cosmic singular exception to the rule that proves my model's rule of everything that is "object", universally, always being in motion / in animation, is that the Universe (U) is never in motion, never has been in motion, never will be in motion, in either space or time since it is the overall "Constant"; the overall totality; the Cosmic All; at once the non-local background Universe (U) to each and every local foreground universe (u) of an infinity)).
Planck Big Bang (E) || Big Crunch (M) / Big Vacuum (C^2)
Energy (E) || Mass (M) / Vacuum (C^2)
M = E / C^2
E = M x C^2
C = 300,000kps (rounded off) = 0 (Universe's 0-point constant)
C = 300,000kps
and / or
C = 0 (that constant of unreachable, unattainable, collapsed -- binary -- Horizon).
Third dimension of the binary twain: planes of, and / or relativity of, 'velocity'.
(past (elastic) (-) --> future (elastic) (+) --> Now (t=0 (constant!))
(pasts (infinities of) (-) --> futures (infinities of) (+) --> Now (t=0 (constant!))
It's a Multiverse Universe.
