An alternate view of fundamental particle structure. This is a brief description of an alternate theory of the structure of fundamental particles (including leptons, quarks, and photons). It assumes forces interact via refraction of either the exchange particle upon the fundamental particle, or the fundamental particles upon each other in the case of the strong force. It further assumes the graviton is a low-energy tachyon, with high (but imaginary) rest energy, and that a pair of gravitons is internal to all other fundamental particles. As a low-energy tachyon with velocity far above c, the frequency is essentially constant (around 4.148 x 1042 cycles per second for the graviton), and the product of velocity and energy is also nearly constant (around c * 34.3 octillion eV). The proto-lepton is in a 1s orbit within the electron, 2s in the muon, and 3s in the tauon. Similarly the 2 kinds of proto-quark are in 1s, 2s, and 3s orbits for the up & down, charm & strange, and top & bottom respectively. The photon has 1 or more proto-photons, each with essentially no rest mass but kinetic energy equivalent to the underlying gravitons, probably in 3 mutually perpendicular planar orbits. The graviton is trapped within the structures by the Lorentz-Fitzgerald contraction, which expands the 7.23 x 10-36m diameter of the various orbiting constituents (derived from a balance of force on them) to fill the circumference of the orbit from the gravitons perspective. Refraction attracts the constituent (since slowing them drops their energy on the side with refraction), but repulses the graviton (since slowing it raises its energy). The 2s and 3s orbits are much smaller for the constituent than 1s, since wavelength drops with rising kinetic energy (rapidly near c).
