5 FORWARD BACKWARD TIME DIRECTION

# The sea of possibilities

Entering the dark galaxy
Let's return to the view sketched in item 15 of page 3 of this storyline. I wonder what it would be for a forward person like me to enter such a dark galaxy. I mean, there is just empty space between us and them and if I cross that space I am there. What happens then?

As pointed out in item 14 at page 3 of this storyline, and page 2 of the storyline QUATERNION GRAVITATION, the backward time vacuum is not that different from forward time vacuum. The Higgs field and the gravitational field remain the same. There only are instead of as vacuum particles, but as long as there are no weak interactions involved, you wouldn’t notice that. In space we observe no special effects around Dark Matter (supposed Dark Matter) nor around supposed Dark Energy. (“Dark” meaning “invisible” and not meaning “backward time evolving” here). So I think crossing the time border is like leaving positively curved space, then one moment crossing a single plane of zero curvature and next enter negatively curved space ( - mark this view is abandoned in the GRAVITATION storylines!). Nothing special is expected to happen there too. A free falling object, approaching the time border in empty space, will just continue its straight world line in the spacetime coordinate system, when passing it, see the scheme below in the paragraph “The diamond”.

Quaternion considerations indicate time just reverses when crossing the time border. Before passing the border, the vacuum marbles equal 1. After passing they equal -1, forcing everything that is in it to evolve backward in time and obey dark mechanics. This means entropic behavior reverses direction.
There is no slowing-down-of-time up to the time border and speeding-up in reversed direction at the other side. Entropic behavior just obeys local laws of physics and keep it so. When passing the time border the time direction of the entropic behavior reverses. That's all there is to time.

I take the CPT theorem to apply here. The CPT theorem states if you have an existable process and reverse time, invert parity and conjugate charge, the result will for sure be an existable process too. If only one or two of them are reversed, the new process might not exist, depending on weak contributions and neutrinos. We did invert parity by changing for and we reversed time. So “to make sure our process exists”, we conjugate charge too. We take the real particles of the backward time galaxy to consist of antimatter.

At page 2 of EXPANSION OF THE UNIVERSE is argued every antimatter particle creates its own backward time evolving vacuum around it (this is calculated in paragraph The calculation of the time border at the same page). Sufficient amounts of antimatter then define a consecutive amount of backward time evolving vacuum around it.

The diamond
Below is an x-t diagram. Matter galaxy A evolves in time to matter galaxy R and then to matter galaxy B. Antimatter galaxy C evolves to antimatter galaxy T and then to antimatter galaxy D, in backward time direction that is. b-b-b-b-b is the time border. Behind S, X and U there is another “b”; S, X and U lie on the time border, at the point just between the two galaxies. For convenience we take both galaxies of equal mass and standing still relative to each other. When a light ray heading for the antimatter galaxy starts at A it would pass the time border at X. The numbers 1 up to 5 are moments in time. If we take the distance to the antimatter galaxy at 10^9 light years, your entire lifetime can be regarded as a very tiny length of time starting at, let's say, moment 3.

Suppose a traveler (not you) would have started at A and travels at near light speed in the direction of X. When it passes the time border at X, what happens then?

According to usual science fiction, taking into account all particles of the traveler and his or her ship soon interact dark (that is: backward time evolving), the traveler reverses time direction and now goes from X to D.

But according to the statement that there is nothing special to see at the time border, one expects a straight line, from A through X to C. But the part C-X evolves in time from C to X, to end there at X at precisely the same state the traveler has when starting from A and arriving at X.

Let's regard first the usual scifi view, travel AXD - but instead we regard travel RST, which is essentially the same kind of travel. We start with the question how many versions of you are there, at the various moments?
1) From moment 1 up to your birth at moment 3 there were no versions of you, of course. Between your birth and your departure at the age of 31, on the travel to the antimatter galaxy, there is only 1 version of you. Between the departure and - but wait.

2) When you were a single photon traveling RST (this means the photon starts at R, arrives at S, reverses time direction there and heads for T) you would arrive at the same moment you left, moment 3. Another photon traveling TUR would also depart and leave at moment 3. R and T would be able to communicate by photons traveling RST back and TUR forth and see each other instantly at moment 3.

3) The conversation proceeds in opposite time directions. The end of their message is observed by us as the start of it and the actual start comes later. For sure. No end without a beginning. Especially when the messaging is email-like, every answer accompanied by all previous texts, it would be very nice to start the conversation, seeing their final text coming in with all previous conversations, conclude there is no need to continue and amused you read all things that you have said if you would have said them.

4) It will anyway be tiresome to always get the answer preceding to your question. One always is tempted to leave out the actual asking of the question since the answer is already there.

5) But they are not stupid too, of course. All this applies to them too.

6) Especially there should be no reason why you shouldn't talk to yourself in the time before your depart on travel RST.

7) Well, if I don't mistake, any point on the diamond could communicate with every other point on the diamond by photons traveling along the same diamond lines. (Then you will need the mirrors of point 10, see below.) You should make agreements about communication frequencies.

8) Well, just like the photons, as you traveled RST, you can travel back, along TUR. So we recapitulate the number of version question now. Before moment 1 there are no versions of you. At moment 1 there is 1 version of you, at the moment of time reversal at U. Between moment 1 and your birth there are 2 versions of you, one going forward in time and one going backward. Between the moment of birth and your depart at the age of 31 there were - but wait, again.

9) Suppose, after having traveled RSTUR, you managed to re-enter your life at the right spot and time when you were 31 years old. But you made a small mismatch, you returned ten minutes before your departure and 100 m aside. You walk the 100 meter towards each other and you - the both of you - shake hands. You talk a little, you wish yourself a good journey, and there you go, the other you, of course. Between the moments of your birth and death there are 3 versions of you all the time, see the picture.

A diamond travel.
You see the moments of your birth and your death.
Moment 3.1 is the moment of departure to the antimatter galaxy.
Moment 3.2 is the return to your place, 10 minutes earlier and 100 meter aside (not on scale).
Travel at near light speed keeps flight endurance within reasonable size (due to relativistic time dilation), but maybe freezing-in is necessary too.

10) Suppose you were a single photon and there are mirrors at R and T, mirroring back you - the photon - to where it came from. When traveling RSTUR, and when you coincide with yourself at R (having same location, direction, wavelength, phase and spin) then the possibility opens the photon has no goal and no source. At a certain moment it just reflects at R and T once and nobody knows it hasn't a source, nor a goal.

11) Suppose you - still a photon - would not precisely coincide with yourself, then there is a second passage at R, at nearly the same moment and place and then heading for (nearly) the same travel RSTUR. And a third, and a fourth. If the photon managed to go around 10^10 times before it is finally absorbed somewhere, all those photons will be there at (nearly) the same moment and place, at the mirror at R and T. And everywhere on the track then, of course.

12) The traveler, “you” that is, can do like the photon, isn't it? Traveling around and copying itself every time it passes R.

As you can see in the picture, the number of you's is changing all the time. If you happen to carry a small excess of electric charge, or impulse or impulse momentum, then the diamond travels violate conservation laws, nearly all of them, and more than once. They anyway violate the conservation of mass-energy. And cause a lot of timetravel inconsistencies. Well, let's end our view on the usual scifi diamond travels. They are fun to think about but not very realistic. Let's shift to the cross travels like AXC and BXD.
