The Speed of Light as a Topological Constraint: Dimensional Resonance in Sixta Theory

In this paper, we propose that the speed of light c is not a fixed cosmic speed limit, but the result of a topological constraint imposed by recursive twist-phase geometry. Within Sixta Theory, c emerges naturally from the harmonic resonance of dimensional embeddings, acting as the fundamental phase-locking threshold for information propagation. The constancy of c is thus reinterpreted as a boundary condition of twist coherence across the 3-to-4 dimensional manifold transition
