Based on the Duality of Time hypothesis from the Single Monad Model, this work introduces and investigates a dynamically generated formulation of self-contained space-time. The resulting physical vacuum is shown to be granular and genuinely complex, governed by real and imaginary levels of time. Within this "time–time" geometry, spatial dimensions emerge dynamically through nested layers of real time, while physical evolution unfolds along the orthogonal imaginary axis. This dual-temporal framework yields a hyperbolic space-time manifold that reduces to General Relativity in the appropriate limit, while offering a deeper ontological foundation for discreteness, causality, and mass–energy relations. From this framework, we derive the foundational principles of ``Quantum Relativity'': the constancy of the speed of light, Lorentz transformations, mass–energy equivalence, and the equivalence of inertial and gravitational mass—without assuming any background or external fields. By reinterpreting the vacuum as a dynamically re-created medium, the theory offers a potential resolution to the cosmological constant problem and opens new insights into mass generation and quantum nonlocality. This formulation offers a mathematically rigorous and ontologically unified approach to quantum gravity, bridging quantum mechanics and general relativity through discrete temporal geometry.
