Compliant to Einstein’s CAP, all analyses of reality must be analyzed in a spin 2 dual manner. As a direct result stable Particles which represent everything must be analyzed as:

Ideal Harmonic oscillating math. Point-waves in the 2 Dimensional Plane perpendicular to the direction of motion (SR-worldline) with CAP-dual Open- or Closed- BC. All possible Bosons are described with Closed-BC & all possible Fermions are described with Open-BC.

Open-BC allow interactions in possible directions, so must has masses > 0 and EM-charge densities <> 0. Open-BC also allow more so-called Particle Families, which can better be specified as Fermi-Families. The only difference between these families are their different (Rest-)Masses > 0.

There are CAP-dual two independent sources of Force-fields:

Non-Zero Rest-Masses & non-zero charge densities.

Only 4D-Spacetime (and 4D-Energymomentum) allow Knots, so only this easy imaginable space allows Fermions.

Analyzing 4D-Spacetime Complete Non-Reducible results in analyzing the sum of an Anti-Symmetrical & a Symmetrical Transformation tensor.

The Anti-Symmetrical tensor has 6 degrees of freedom and must be described by the direct product of a Fermionic Source and a Bosonic set of Force Fields: 6 = spin 1/2 x spin 1.

The Symmetrical tensor just is the Gravitational-field with it’s sources the rest-masses > 0: 10 = spin 1/2 x spin 2.

All masses must have non-zero charge densities, compliant with the CAP.
