Structured Vacuum Theory: Rethinking the Foundations of Physical Reality

Structured Vacuum Theory (SVT) proposes a fundamentally new ontology for physics, in which the vacuum is not a passive background but the sole substance of reality. Within SVT, particles, geometry, and physical constants are not primitive entities but emergent phenomena arising from a structured vacuum and its excitations. Using a minimal action with two metrics and a constitutive scalar field, SVT derives an explicit equation of state for the vacuum, recovers General Relativity as a limit case, and predicts observable effects—including galactic rotation curves—without invoking dark matter. This work presents the mathematical formulation, field equations, and phenomenological consequences of SVT, offering a unified framework in which both matter and geometry emerge from the vacuum itself.
