What is changing is the ability to change the ability to change. Nothing else exists at all.
And “energy” is that ability to change actually changing in the two forms of “potential to actually change” and “actual changing”, “potential energy” and “kinetic energy” or “PtA” and “Affectance”.
Energy can be expressed as the potential to cause change plus all of its time derivatives;
PtA
dPtA/dt
dPtA/dt^2
dPtA/dt^3
.

.
PtA is equivalent to “electric potential” in physics.
That question takes a lot of careful conceptual communication to answer. Let me give it a shot.
If we begin with the idea that every point in space has a potential to affect the potential next to it, we have to conclude that since there is nothing stopping it from doing so, such affecting will immediately take place and thus every point in space will immediately begin changing as it begins changing the points around it. Again, what is changing is only each point’s ability to change the other points. That is the fundamental makeup of physical reality.
Propagation merely refers to the chain of affects as point A affect point B which then affects point C which then affects point D and so on much like the domino effect.
That is the simple part. But logic dictate that there is more complexity involved because as each point affects the next, it is using up the amount of potential to cause that affect merely by actually causing it and thus, in effect, as any potential gives to another, that other is taking from the first.
This is like a rich man giving his money to a poor man. It is said that the wealth is passing to the poor man. But it is necessarily also true that the poorness is passing to the rich man. Thus for every direction of increasing affect, there must be a reverse direction decreasing of affect (which happens to be why energy is necessarily and always conserved).
And what gets complex is the fact that such increasing and decreasing of each PtA at each point causes each of those points to pass the affect along to the next point in line - propagation. And such is always happening in all directions at the same time.
If we take the concept of varied potentials to affect, PtA, distributed across a small line, we have to conclude that propagation will occur in both directions along that line.
But as that propagating takes place, each point is being affected from both sides by what was coming toward it from its left and also what was coming toward it from its right. Thus the point itself has the addition of both propagating affects.
That was still the easy part. What gets fun is realizing that as each wave of forward affecting propagates, it includes both increasing PtA affects as well as decreasing PtA affects traveling in the same direction at the same speed. And that is happening in both directions.
In the above pictorial, the red and blue segments indicate the decreasing and increasing affects, respectively. But note that there is increasing headed in both directions as well as decreasing in both directions. As those affects cross at each point, they add to the points PtA. Thus if both were increasing, that point increases more. If one was increasing and the other was decreasing, that point has the result of the addition of the increasing minus the decreasing and thus might not change much at all. But even if a point does not change in its total PtA, the propagation does not stop (it takes a lot more explanation to go into why it doesn’t).
So what you see as the green line in the pictorial is the actual result of propagating affects. It is a line that would appear to be rapidly and turbulently swaying up and down with no apparent pattern. That is what causes the “springiness of space” noted by physicists 100 years ago. That line represents the true and real state that all space is actually always in, always has been in, and always will be in. That fact can never change.
Modern quantum physics ontology basically agrees with the exception that they claim that such turbulence is due to magnetic bubbles popping into and out of reality on a Plank level, without cause. RM doesn’t accept causeless events as logically coherent.
RM’s Affectance Ontology vs Quantum Physics Ontology
RM: The EM turbulence of space is due to a maximum change rate causing a finite propagation speed of EM waves
QM: The EM turbulence of space is due to uncaused magnetic bubbles randomly popping in and out of reality.
QM gains statistical accuracy merely because they don’t need to know why things are happening in order to measure them. RM merely gives logically coherent explanation as to Why they see what they see and affords far more precise predictive potential.
