Quantum FFF Theory is a semi classical theory because it describes reality by the real collision and transformation processes of real but different shaped symmetric sub quantum rigid stringy particles.
These particles are supposed to be based on only one original transformable ring shaped massless virgin particle called the Axion/Higgs particle assumed to be the product of the symmetric cyclic big bang nucleus as the creation of a limited symmetrical multiverse equipped with an even number of material and anti material universal bubbles.
The Q-FFF theory is called Semi classical because in addition to the ring shaped transformable rigid string particles, all universal bubbles are assumed to be each others Charge Parity mirror symmetric universal bubbles which are assumed to be instant entangled down to each individual string particle created out of the Axion Higgs splitting cold Big Bang.
The sheer simplicity of such a system is perhaps the reason that I could not find comparable proposals for theories of everything.
