Motor Dimension Theory Motion as a Fundamental Coordinate and Its Physical Consequences

A physical model is proposed in which motion is treated as a primary entity, geometrised via an additional compact spatial dimension μ — the motor dimension. Time t is demoted to the role of a parameter that measures the relative frequency of motions. Four postulates are formulated, from which a fundamental five-dimensional action is derived, explaining mass quantisation and the origin of inertia. It is shown that observable reality can be represented as a discrete sequence of three-dimensional "frames" that refresh at a frequency fμ = c/(2πRμ). From the anomalous magnetic moment of the muon, a bound on the compactification radius Rμ ≲ 2×10⁻¹⁸ m is obtained, corresponding to the first motor-mode mass M₁ ≳ 100 GeV. Falsifiable predictions are proposed: towers of motor excitations of particles, anisotropy of ultra‑precise clocks in a gradient of the motor field, and the hypothetical possibility of extracting energy from a gradient of the motor potential. The theory is consistent with known experimental data and opens new directions in fundamental physics.
