""" Soliton Dynamics Module ======================= Implements N-body simulation of KnoWellian Solitons (fundamental particles) emerging from light-speed primitives. Physical Model: - Primitives: Point-like entities constrained to |v| = c - Types: Control (+1) and Chaos (-1) - Interaction: Perpendicular inverse-square law - Emergence: Stable torus-knot structures form spontaneously The simulations demonstrate: 1. Spontaneous soliton formation from random initial conditions 2. Stable rotating "cosine string" structures 3. Quantized angular momentum (proto-quantum numbers) 4. Control-Chaos interface equilibrium (D-brane) This provides a quantum-deterministic foundation showing how particles emerge from the KUT field dynamics.
