One of the long-standing philosophical questions is whether there is a reality to what humans experience. One of the famously controversial ways to looking at this is the holographic principle, which proposes that everything we experience in 3D is merely a holographic projection of 2D information on the outside surface of the universe.
That raises a second question, which is how my experience of reality is connected and coordinated with yours. This introduces time into the problem. Special relativity (SR) has a principle, in the form of the relativity of simultaneity, that says 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).
In our Cordus theory of time, we examine some of these questions. We look at the question of how multiple bodies interact, and how the coordination arises. We have already identified that there is no master clock, but if that is lacking then we still need a coordination mechanism. There is a connectedness of phenomena that are at different geometric locations. It seems that spacetime is continuous, because it seems that it is possible to coordinate the two phenomena in time. We show that the two phenomena are linked, because they share the same fabric.
According to this new perspective, any communication between two objects is a result of photons, or massy particules, or fields, and these cause positional constraints on the other, i.e. the geometric location of the reactive end is affected by the communication. A phenomenon that occurs in one volume of matter, be that combustion, noise, motion, etc, thereby communicates that to other matter around it. Consider one volume to be my body: my speaking transmits forces to the volume of air immediately around me, which in turn propagates the dynamic displacement throughout its bulk, so that the membrane in your ear is displaced, and you hear the sound.
In general the phenomenon is that one volume of matter causes an effect in the second. The interactions at the most basic level all require frequency cycles, so this causes temporal causality. Thus we infer:
It is not a master clock that accomplishes the temporal connectedness of phenomena that are at different geometric locations, nor does it require continuity of spacetime per se. The piece-wise communication, via discrete field interactions of the fabric, between adjacent volumes of space (matter and fabric) applies spatial consistency to time.
Any one particule A receives discrete forces (fields) from all the particules (many Bs) in the observable universe. Space within the universe is therefore filled with a mesh of discrete fields in transit, which in the Cordus theory is termed the fabric.
Fabric time is the mutual interconnectedness of matter particules spread over three-dimensional space. This occurs via the fabric, comprising discrete field forces for electric-magnetic-gravitational interaction. Not strictly a time, this is rather a coordination of events across space.
In this theory the fabric, and the EMG fields it carries, causes a connectedness between particules. They respond together, even if in a slightly delayed manner as their separation increases. There is therefore a coherence and smoothness to the interaction between particules, mediated by the fabric. The resulting interaction stitches together three-dimensional domains of space (matter and vacuum-fabric) into a macroscopic collated time. This level of time passes more slowly, due to the many tiny delays required for particules to react to each other, given the dissimilar-frequency and phase-differences between the particules. This, Cordus suggests, is where the arrow-of-time arises, and what general relativity perceives as spacetime. This is also the macroscopic level of physical time, and hence where our perception of time first arises.
This Cordus concept of 3D fabric affirms the general relativity perspective of spacetime. It also provides an ontological answer to one of the earlier questions: it suggests that spacetime has a quasi-substantial status (comprises discrete force) but has no universal time-signature per se, and mainly represents merely the relationships between bodies.
