The first thing that you will prove and demonstrate with merely the prototype is exactly how and why subatomic particles form. With a larger system, the monoparticle affectance density equation (“particle energy density”) can be demonstrated and proven, along with its dependence upon ambient affectance density.
$$Ad = \frac{1-Ab }{1 + 4\pi((x-a)^2 + (y-b)^2 + (z-c)^2))}$$
Such will prove to Science the make of subatomic mass particles and that they will alter their mass energy content in accord with how close they are to large masses, such as Earth.
The next thing to prove and demonstrate will be the cause and make of mass gravitation. To the disappointment of Quantum Physics, you will prove that there is no “graviton” in the physical universe (the proposed force-of-gravity carrier). The only particle associated with gravity is the mass particle itself. Along with this proof, it will become obvious that gravitational migration is not due to a magical force emanating from mass particles, but rather due to the gradient affectance field between masses.
And inherently you will be proving that extreme outer space is different than space between the planets and thus gravitational effects should be expected to be a little different. This is a part of the confusion related to cause and make of “dark matter”.
That much is with merely the first stage prototype. Charged particles get a little more sophisticated and interesting. Molecular structure and static magnetism demonstrations might require a larger system.
