Thickness Structure Hypothesis Dynamics - Unified Equation of Motion

Description This work presents a unified dynamical framework based on the Thickness Structure Hypothesis, in which quantum behavior, classical relativity, nonlocal correlations, and measurement irreversibility emerge from a single underlying geometric structure. The theory introduces three fundamental variables—thickness density p(x), structural difference Δf, and structural tension γT—whose interactions define a universal phase diagram consisting of Stable, Composite, and Core phases. A covariant action is constructed using p(x) and the spacetime metric gμν, from which all dynamical equations follow. Variation with respect to p yields a quantum‑like gradient term, while metric variation produces a fully expanded stress–energy tensor for the thickness sector. The phase diagram is encoded in a Landau‑type structural potential Φstruct(Δf,γT), whose gradient generates a structural force that governs transitions between phases. Combining these elements leads to a unified equation of motion that naturally incorporates (1) the quantum gradient force, (2) the relativistic geodesic term, and (3) the structural force determined by the phase diagram. In the limit Φstruct→0, the theory reduces exactly to general relativity. For many‑body systems, a single thickness field Φ(x1,…,xn) defined on configuration space accounts for nonlocal correlations without invoking action at a distance. Measurement irreversibility arises from a Core‑phase transition driven by Δf and γT, providing a structural explanation for wave‑packet collapse. This document includes the full derivation of the unified dynamics, the explicit form of the structural potential, the complete stress–energy tensor, and the mathematical consistency analysis ensuring covariance, conservation laws, and internal closure of the theory. The purpose of this release is to establish a citable, timestamped reference for the Dynamics sector of the thickness‑structure hypothesis. All terminology, definitions, and conceptual structures introduced here originate with the author. Unified Equation of Motion The covariant variational principle, applied to the thickness density p(x) and the four‑velocity field uμ, yields a unified equation of motion in which all geometric (general‑relativistic) effects are absorbed into the covariant acceleration on the left‑hand side: DuμDτ=−∇μln⁡p+Fμ(Δf,γT). Here, the term −∇μln⁡p arises from variation of the covariant action with respect to the thickness density p, and plays the role of a quantum‑like gradient force; the structural force Fμ(Δf,γT)=−∇μΦstruct(Δf,γT) is generated by the Landau‑type structural potential that encodes the Δf–γT phase diagram. This single covariant equation governs all dynamical regimes—quantum, classical, relativistic, and measurement‑induced—within one unified framework. In the limit where both ∇μln⁡p→0,Fμ→0, the equation reduces exactly to the geodesic law of general relativity.
