I really enjoyed reading your essay, and also rated it to highest.
On the other hand, I feel sorry of the the gap between human understading and the effort to approach simplicity by overcoming the difficulties of complexity.
In other word, to reveal simplicity of fundamental physical theory by thinking deeply with the Nature's puzzling and related effects is quite difficult, but what most difficult is Human understanding.
Since these two problems are interlinked we should prioritize and focus first to find ontological solution modern physics before finding a answer to fundamental related questions.
My previous essay I have only focused to hypothesis that links theories together in terms of fundamental particle and force. My current essay I focused more than half to point out needs for ontology related issue rather than answering the fundamental question. After evaluation I realized that answer is almost meaningless without good ontological/philosophical ground, that is why give more importance to essays focusing ontological issues. There are many essays to read but from the ontological point of view, I think that Vladimir I. Rogozhin and Maxim Yu. Khlopov, may be interesting essays
One very intresting example is that Natural Philosophy set good foundation Nature's fundamentals by quantizing in terms of elementary particle and force equilibrium in terms of neutral and charged including similarities of both macro and micro levels such as;
Formulaions Newton's and Coulomb's law
Experimentals Cavendish's and Coulomb's experiments
Implications Newtonian and Maxwellian two planet-like systems in different scale.
But things got strange in 20th doe to interpretation without ontology even terminology are some how affected,
In general I agree your conteptual explanation, some points I appreciated;
"simple components does seem to imply increasing physical dimensions but we'll test the 'more simple' aspect of reductionism, taken down to perhaps it's most ridiculous extreme, to find a most fundamental cause".
"This domain limit is also the lower end of electromagnetic (EM) coupling. Electromagnetism (EM) permeates, lights and connects the universe, interacts with matter and allows communication."
"a real synthesis of quantum and relativity theories requires not just technical developments but radical conceptual renewal." and suggested a 'lack of imagination' was the problem, that we should keep looking, and; ""...the new way of seeing things will involve an imaginative leap that will astonish us. In any case it seems that the quantum mechanical description will be superseded."
elementary character e rests upon fundamental character of matter (particle), combination with it's potentail difference 1V becomes elementary energy 1eV = 1.6テ--10^-19J, on the other hand mass included 1.782テ--10^-36 kg. see also wikipedia. I think even maximum ratio of wavelengths of electron-photon to the pot.difference and ....
Regarding the context, what is real meaning of "elementary" and it's relations to mass value and energy value.and to Fundamental.
