This paper presents a mechanical derivation of the fundamental constants and relativistic phenomena within the framework of the Quantum-Crystalline (QC) medium. By modeling the vacuum as a discrete lattice of rotating spins, the speed of light c is demonstrated to be the elastic relaxation limit of the spin-lattice rather than an arbitrary postulate. Relativistic mass increase and time dilation are interpreted as macroscopic consequences of viscous saturation and temporal congestion, respectively. Furthermore, the cosmological redshift is derived as a "smearing" effect caused by the asymmetric energy return of spins in low-density cosmic voids. This framework provides a deterministic mechanical alternative to the Dark Matter and Dark Energy hypotheses by attributing these phenomena to the dynamic viscosity (etaqc) and the Z-thickness (hqc) of the spacetime fabric.
