Abstract

The Unified Theory of Ontological Expansion (UTOE) argues that the universe is not a completed four-dimensional manifold but an ongoing process of ontological actualization. Time, on this view, is structurally non-completable: local temporal progression occurs, yet no globally completed totality of time exists. This is formalized by the directed relation Existence = T not leading to T completed indicating that temporal becoming is oriented toward completion without ever attaining it, together with the global condition T tends to infinity UTOE rejects block-universe eternalism by treating spacetime as the product of a continuous phase transition from ontological potential to actuality. The arrow of time is thereby grounded in the structure of reality itself rather than in entropy, boundary conditions, or observer dependence. Becoming is not an epistemic illusion but an ontological feature of the universe.
