Space-time existence manifests itself in space and time. We do not know how orthoexistence manifests itself in a pure state (without space-time existence), but in the presence of space-time existence it may be at play by its influence on this existence or by its interaction with this existence.
Referring to (V) we can no longer state that the material exists forever, since in defect of space-time existence we do not know whether the time exists. Statement (V) for space-time existence should be obviously ruled out, since formula (XII) gives the world outside any space or time reference. The world may sometimes be orthoexistence, and at other times space-time existence plus orthoexistence.
Experiment (VI) is likewise definitely valid. The present existence does not exist ever, it has a zero-time commencement in orthoexistence. Hence, by introducing orthoexistence as a philosophical operator, the two fundamental experiences (II) and (VI) became compatible. The attempt to rule out contradiction (VII) became possible by cogitating not-existence as an orthoexistence.
We have not made any attempt to dispense with the two fundamental experimental results (II) and (VI). However, the compatibility of these results entails that not-existence should be regarded as a certain existence, hence as something outside what we empirically know to be existence. That something cannot be just a logical or a philosophical operator, since orthoexistence is a concept deduced from experimental premises, and according to our whole scientific experience, we expect it to be subject to experimental verification.

Given that the particular coordinates of orthoexistence are not known, one could hardly try to decipher the dynamics of orthoexistence. We can only model the general dynamics of existence, taking orthoexistence into account. The immediate question is: when space-time existence arises, what happens to orthoexistence ? Does it vanish or does it continue in a certain way ? Given that space-time existence and orthoexistence are interchangeable and are both material, it is just normal that they should satisfy a general conservation principle:

XIII. L = E(space-time existence) + H(orthoexistence) = constant.
Here, we have obviously used our scientific experience as applied to material processes. We do not know the actual way in which the quantity "L" relates to mass and energy - the main quantities of interest in existence conservation processes - but it might be of the nature of these quantities. If extrapolated to orthoexistence the conservation principle raises the question of the meaning of quantity H as a function of what might be pertinent to orthoexistence. The conservation principle does not apply to space-time existence. Instead, it can apply to the world. It is only under certain conditions and in a first approximation that E(space-time existence) <> constant. The space-time existence conservation processes are no longer strict: existence might vanish, it might arise, and hence develop between these two events.

By virtue of the conservation principle, the world is a constant and existence may assume the evolution patterns illustrated in Fig. 50 (a, b, c, d).



Fig. 50

In case (a) existence would arise and vanish without exhibiting an evolution, whereas in case (b) it would exhibit a certain rise-and-fall dynamics.
Other patterns may be also envisaged (seecases c and d). In case (c), existence would spring from a nucleus and expand to infinity to vanish at a given time. In case (d), two types of existence - one positive and the other negative - would be alternating. Referred to the general philosophical principle expressed in the figure, the above diagrams suggest only one phenomenon, namely the emergence and the cessation of existence.
Concerning the representation with respect to time, which is an attribute of space-time existence, the time laps between two existences is of no relevance. That is why the time interval tcin Fig. 51 is meaningless. Space-time existence emerges with time proper and vanishes together with its own time. Space-time existence vanishes together with its own space and emerges together with its own space.



Fig. 51

Any space-time existence develops in its own space and time. A certain space-time existence is alien to another space-time existence. The time and the space associated to various types of existence are incompatible among themselves.
Hence, any such existence originates with time, which begins thus to "flow". The above diagrams describe only one phenomenon, i.e. the emergence and the disappearance of such an existence.
As concerns the representation with respect to time, the time being an attribute of such an existence, the time periods between two existences are of no significance. This explains why the time interval tc in Fig. 51 is meaningless. A space-time existence emerges with time proper and vanishes with its own time. Such an existence vanishes with its own space and emerges with its own space.

A space-time existence develops against its own space and time. The times and the spaces of different such existences are incompatible.
