Here, the concepts of global and local effects of sinertia are introduced to the theory. The action of motion must account for two components acting upon the particle while in motion; one is the field the action takes place in (with a dependency on available sinertia), and the other is the effect the motion of the particle has on the particle’s pinertia and available sinertia. The first is considered a global effect, and the second is considered a local effect. This section only considers the global effect, then in the following sections, both global and local effects are defined, discussed, and shown how they affect a coordinate transformation. Postulate 4 states an attribute of space is to maintain an equilibrium of sinertia, meaning if a change in sinertia takes place at a location, the surrounding space will (via flowing sinertia into or away from the location) attempt to bring the difference between the two locations sinertia to zero. The theory’s concept of global and local effects is divergent from Einstein’s GR. Einstein does not consider a local effect vs a global effect per se. His field equations affect the entire field, and they are based on energy. All energy, according to Einstein, is not only transferable to other forms (like rest energy, photon energy, and momentum); the energy also produces curvature in space-time. Thus, all energy produces a gravitational potential about it that affects the entire field. NUVO theory does not agree with this opinion.
The flow (or flux) of sinertia implies mathematically space is a source of sinertia and mass acts as a sink to sinertia. Postulate 1 was introduced using the word propensity for sinertia to reflect space intrinsically maintains the coupling to mass. This coupling maintenance implies a force continues to act upon a mass to “hold” it to space. When a mass is introduced to space, it reduces the sinertia at its location. This reduction induces a flux of available sinertia from surrounding space to flow toward the mass, generating a reduction in sinertia. This reaction by space to maintain equilibrium generates a field in space, thus a mass at one location will influence a space’s sinertia at a different location as the reaction to equalize the field propagates through space (At this point in the theory’s development, the reaction is assumed to propagate at the speed of light). As the field’s gradient is propagated, the sinertia is changed from equilibrium to non-equilibrium at a location. Sinertia has a higher magnitude in one direction and a lower magnitude in another direction (a gradient). This in-equilibrium causes a mass to be unequally coupled to space. NUVO theory holds that the unequal coupling to space causes a change in inertia (Newtonian) and, thus, acceleration for the mass. This scenario implies Newtonian gravity will be viewed as a force. The difference between the theory and Newtonian mechanics is the propagation effect (as sinertia changes, it must propagate through the field) is not instantaneous, and the change in sinertia changes the time as measured by observers in the field. This effect of mass-reducing sinertia is a global effect, and it changes the field about it as it propagates through the field.
Another effect on sinertia is when a mass travels through a field, there is the aforementioned global effect of the change in the field due to the moving reduction in sinertia, this is propagated through the field. The movement of the mass through the field also affects locally the available sinertia for the mass in motion. The flux will increase as it moves through space, thus changing its sinertia relative to the field. This effect is a local effect.
