Where did time come from?

The Cordus theory of time suggests that time started when the universe started.

To the level to which Cordus can penetrate, time is a consequence of the frequency oscillations of particules.  Its rate is thus determined by the mass of the particule, in turn how it is assembled and from what subcomponents. In that sense even massless particules (photon, neutrino) have frequency and therefore time. However the forward arrow of time arises where coherence lets off and decoherence starts. This discontinuity in the physics of time occurs at different levels of assembly depending on temperature and homogeneity. Time therefore comes from the frequency oscillation of matter, which in turn comes from the primal photon(s) at genesis.

Is time a dimension?

According to the Cordus theory, time  is not a dimension. It is not a ratio variable. Nor can it be traversed  backwards and forwards like a position in space. It is neither smooth nor infinitely sub-divisible.  It only looks that way when viewed from a sufficiently high level of assembly, hence the approximations of the classical mechanics and of spacetime.  In the Cordus view, time is more like a patchwork of cause-and-effect ratchets between sub-microscopic domains.

The way matter interacts with matter via discrete electro-magnetic-gravitational (EMG) forces, causes the matter particules to move into different states (e.g. a new position in space) at each frequency cycle. These interactions are irreversible, because each particule that moves out of its previous position changes the whole universe around it (its future light cone) because it is now emitting discrete fields from a new position. This is where the arrow of time arises. Hence time arises as ratchets of irreversible disturbances between particules. We can then show how this aggregates to time at the atomic level, and then to our macroscopic level.   So in this model time is an emergent property of discoherent matter.

  • Revisiting Special Relativity: A Natural Algebraic Alternative to Minkowski Spacetime (plosone.org) [This article shows how Clifford alegebra can be used to model spacetime as a multivector. Specifically, they include a rotating bivector. Then they  ‘interpret time as an angular rotation at the de Broglie frequency’  of the particle.  We suggest this is a consistent with the Cordus interpretation of time. Both approaches state that time is fundamentally generated by the frequency of the particle. ]

The Rietdijk–Putnam argument and Penrose’s Andromeda paradox

Perhaps surprisingly, this is a continuation of the previous topic of time. It concerns how events are ordered in time.

Special relativity (SR) is based on  the relativity of simultaneity, that the order in time of two spatially separate events cannot be determined  absolutely, but instead depends on the motion of the observer. Thus it is impossible to order two events in time if they occur in different places (hence difference frames of reference). There is no preferred inertial frame in SR. Taken to its limits this suggests that people live in different states of the universe depending on their relative velocity, hence the Rietdijk–Putnam argument and Penrose’s Andromeda paradox.

Here is how the paadox is expressed:

“people pass each other on the street; and according to one of the two people, an Andromedean space fleet has already set off on its journey, while to the other, the decision as to whether or not the journey will actually take place has not yet been made. How can there still be some uncertainty as to the outcome of that decision? If to either person the decision has already been made, then surely there cannot be any uncertainty. The launching of the space fleet is an inevitability. In fact neither of the people can yet know of the launching of the space fleet. They can know only later, when telescopic observations from earth reveal that the fleet is indeed on its way. Then they can hark back to that chance encounter, and come to the conclusion that at that time, according to one of them, the decision lay in the uncertain future, while to the other, it lay in the certain past. Was there then any uncertainty about that future? Or was the future of both people already ‘fixed’?” http://en.wikipedia.org/wiki/Rietdijk%E2%80%93Putnam_argument

The Cordus theory of time, offers a way to interpret the situation. In doing so it dissolves the paradox, as will be shown. Here is how the explanation works.

First, whether this is even a paradox is doubtful, because the two people, A and B, in Penrose’s Andromeda thought experiment cannot know, at the time of their meeting, what events are transpiring far away in their difference versions of the universe. So what happens in  Andromeda is unknowable to the people at the time, and any difference in perception of remote events (whether or not the aliens have decided to invade Earth) is likewise unknowable.

Therefore there is no contradiction in world-lines at the time of the meeting, and hence no paradox. It only appears to be a paradox to us because in a thought experiment we can ‘know’ what our subjects themselves do not, which is what the aliens are up to.

Penrose ponders whether, at the time his subjects were meeting, there was any real uncertainty about that future, i.e. a predetermination type of question.  But that assumes that A was already in a version of the universe that was more temporally advanced than B, which is not the case. He was only in version of the universe that would differ in simultaneity from B, if he had continued with his motion relative to B. But at the ppoint in time and space where A and B meet, they are in the same frame. Any subsequent velocity would distance A from B, and any communication from A to B would then be limited by light-speed. But that limitation did not apply at the moment of their meeting. Thus we suggest that the act of meeting is key to the paradox, and much of the paradox arises simply from an ambiguity in Penrose’s defintion of meeting.

Or to look at it the other way, person A had not at the time of meeting B been able to realise the potential advantage of foreknowledge that his temporal advancement might seem to promise. He only experiencees accelerated passage of time after he leaves the meeting, by which time it is too late to tell B. Also, he does not actual have information about the aliens at the time of meeting, but only potentially in the future. Nor would he ever be able to have that information early, since the information on which that knowledge was based (i.e. what decision the aliens had made) could only reach him at light-speed, by which time both he and his acquaintance B would both have moved forward in time (moved on the Minkowski diagram).

Nor does B have any ability to change the unfolding decisions of the aliens, because to do so would require sending a signal back to Andromeda which would also take too long (it would only be received by the aliens after they had already made their decision).

So while A might appear to have the benefit of advanced information about the alien’s plans, that advantage cannot be realised, and therefore that information cannot be transferred to B either, and B has no real ability to communicate that information into her retarded version of the universe, and therefore has no ability to cause her retarded universe to diverse from that inhabited by A. Therefore she cannot tamper with her retarded version of the universe to change the future. There is only one world-line for the universe as a whole.

Therefore what is decided by the aliens stays decided, and to answer Penrose, there is no uncertainty about the future. The future of both people is not already ‘fixed’. That’s quite the wrong way to think about it. instead it is simply indeterminate. The situation only looks like a paradox to an omniscient external observer (i.e. ourselves) who knows what A and B might know in the future.

Thus another way to dismiss the paradox is to point out it employs circular logic: it requires its observer to be in a highly preferred reference frame, free of the relativity of simultaneity, which of course is not-permitted by special relativity.

The bottom line is that the Cordus time theory suggests that there is only one reality for the universe, and that what happens stays happened, though observers in different situations (frames of reference) might get to know of it at different times. But since they are in different situations they cannot communicate that knowledge to the other. So there is no advantage (and no paradox) in the relativity of simultaneity.
