Let me see if I can clarify something here (again with Rational Metaphysics, sorry);
Imagine that you have a region of space that has a high density of non-particle “space-stuff” (call it what you will, in RM it is called “affectance”). And you also have another region of low density space stuff.
You already know that a particle is a wave of that space-stuff formed of high and low peaks swirling in a knot (of whatever design). But now think what you get if you form a particle within each region. In the high density region, you have a particle of high density waves and in the low region, you have a particle of low density waves.
But a particle is a particle due simply to the fact that it doesn’t disintegrate into its surroundings as a radiant wave does. Now what would you think would happen if those two regions came close to each other? The high density flows into the low as the low infiltrates the high. So the regions merge to become more uniform in density. But what of the non-changing particles?
They each represent a concentration of their original space density particlized and thus not changing. So even though the region is becoming more uniform, the particles are not, yet they still “want” to merge due to the difference in their relative density. The space-stuff within each is still attempting to merge, but the particle arrangement doesn’t allow merging. The particle is quantized. The density of the space-stuff between them must gradually become the other and thus leave a gradient. They literally “charge” toward each other as high attempts to fill low (or vsvrsa if you like).
Now if the two particles are of the same fundamental form such as an electron and a positron, they actually will merge once they collide and breakup their particle nature, emerging as photon waves with no net “charge” because they have now merged their densities leaving only a ripple of equally high and low areas chasing each other - a photon.
But in the case of a proton and an electron, we have a different situation. They still both represent high and low space-stuff density locked up into a knot, but they are not of the same form. One can push space stuff, but one cannot pull it. Due to that fact, we can obtain very high concentrated particles of “positive” (high density) stuff that got “pushed together”, but we cannot get such high concentration of low density stuff because we cannot pull, we have to wait for the high density to leave on its own accord much like waiting for the air to leave a balloon. You cannot pull the air out of a container, but merely push it out or offer a lower vacuum for it to rush into - at its own pace.
But along with getting a high density of space stuff pushed together so as to form a positive charged wave, we can get a different effect due to the ramp of increase involved in a wave, the rate of its changing. That rate of change is what causes what we call inertia and mass. So when we push positive stuff (high density) together quickly, we create a mass from the charged stuff, not merely a concentration of charged stuff. And thus a proton, representing such an occurrence, has a higher mass as well as a higher density, constituting a higher concentration changing (matter), The wave fronts within the proton are much steeper than in the electron. It is due to that difference that they cannot merge because they cannot ever exactly overlay each other. But instead they merely hang around each other pining, forever unsatisfied (thus no need for the mythical “weak force” described in physics).
That effect is also why we have only electrons and protons forming atoms and never positrons and negatons. Although we can create the anti-particles, they are not mathematically stable because a vacuum (a negative) is not the opposite of a concentration, but rather the lack of it. Regardless of any other disturbing effect, they will disintegrate. Regardless of science’s speculations, you can never have an “anti-universe”.
