This paper proposes Universal Field Theory (UFT), an ontological interpretation of quantum mechanics in which the Universal Field is taken to be a real structure containing all physically possible configurations permitted by the laws of physics. Observable physical reality corresponds to the subset of configurations that become realized as excitation patterns within the field. In this framework, quantum probabilities arise from the density of realizable configurations encoded in the wave structure of the field. The approach preserves the predictive formalism of quantum mechanics while offering a unified conceptual interpretation linking field ontology, configuration space, and the emergence of physical reality.
