Cool idea. How do you visualize this energy that passes between electrons and protons? What is it?
Size is completely relative, if we are to look at the issue logically. “Big” and “small” are objectively meaningless, an atom is huge compared to a sub-particle, a star is tiny compared to a galaxy, etc. If size is relative, and also space and time are relative, which we know they are, then following that logic through without artificial bias or restriction we are left with a picture of reality that is, if not “fractal” (it very well might be) then at least like an infinity of Russian dolls, extending outward and inward in all directions without limit. Which actually makes sense, because on what basis ought we conclude there to be an absolute limit upon reality? If you think about it, the idea of a limit, edge or “end” of reality is entirely illogical.
Space-time is probably a pure mathematical construct, an infinite geometric matrix on which, at every point to varying degrees, graft “forms”, basic relations, that we think of as fundamental particles or symmetry field-energies. But it gets even more interesting, because the infinite geometric matrix itself becomes, at sufficient relative distances/sizes/times, a sum singular point of energy, form or light, i.e. viewing a portion of reality which itself is sufficiently smaller or distant in space or perhaps also in time from one’s own portion, we can only experience or measure this other portion as a “point” of fundamental energy or form. At first these points would appear heterogenous, shifting their energy or location in minute ways, then as certain greater relative distance is attained they would be seen to homogenize, become pure static potentials, either existing or not, “jumping into and out of existence”; at still sufficiently greater relative distances these points would appear to vanish entirely from existence, they would be absolutely unknowable to us.
Thus, by virtue of what we are as such-and-such kinds and scales of beings, there are subjectively-imposed, relative limits to reality, or rather to our potential experience of reality. It would be a logical mistake to assume these limits are objective, are a part of reality itself.
