The reconciliation of General Relativity with Quantum Mechanics is the primary objective of modern physics. This paper proposes a unified framework by redefining the nature of time from a geometric coordinate to a physical material with mechanical properties. This paper introduces the Alpha-Metric Tensor, where the vacuum is permeated by a scalar field (α) representing Chronometric Impedance and Chronal Rigidity. By treating spacetime as a "stiff" lattice rather than a fluid, we derive a mathematical unification where Gravitation, Electromagnetism, and nuclear forces emerge as different mechanical phases of the Alpha field. This paper calculate the mass-equivalence of the temporal field, determining that one second of causal spacetime contains approximately 163 grams of inertial mass, providing a structural explanation for Dark Energy. Furthermore, this rigidity resolves the black hole singularity problem by imposing a finite elastic limit on spacetime curvature
