Time and Universe Creation, Existence and Destruction

Space and time remain among the most profound unresolved problems in fundamental physics. From classical Newtonian theory to Einstein’s theory of relativity, extensive theoretical progress has been made, yet these frameworks have not fully captured the true nature of space and time. A complete understanding of space–time would directly illuminate the origin, existence, and eventual fate of the Universe. The interdependence between space and time is such that their unified description governs the conditions underlying cosmic creation, persistence, and possible destruction. In this work, we emphasize that a consistent treatment of space–time is capable of explaining not only the emergence and stability of the Universe but also the diverse dynamical behaviours observed across different cosmological phases. This perspective highlights space–time as a fundamental organizing principle linking the Universe’s origin, evolution, and ultimate destiny This work proposes a conceptual and mathematical framework in which space and time are reciprocally constrained such that their product remains invariant. Within this formulation, we described time formula and its current span is about 〖10〗^ (-29) second and derive that universe created within 401 seconds and it is expected to persist in an existence phase of approximately 1380 billion years. we show how limiting transitions of this relationship naturally give rise to cosmological creation, evolution, and cyclic re-initiation
