This scientific work presents the VACIA_Ω Theory, a unified and empirical extension of the base theory "Active Cyclic Self-Regenerating Vacuum." Its main purpose is to establish a minimal and falsifiable structure that integrates particle physics and cosmology, resolving the mystery of Dark Energy.The theory maintains its fundamental principles and extends them as follows:Nature of Dark Energy (Active Vacuum): The active vacuum is described as a Nambu-Goldstone Boson type scalar field that possesses an energy potential with periodic behavior. The parameters that define this potential are derived directly from first principles of physics.Controlled Dissipation Mechanism: It introduces a dissipative channel (an energy loss process) that is strictly limited. This mechanism only operates in late and very short-duration cosmological "windows," ensuring an exact return to the standard cosmological model (ΛCDM) outside these brief periods of activity.Unification Architecture (LQGGUT): The theory provides a coherent structure in the high-energy limit (UV) that successfully derives the symmetry group of the Standard Model, the three families of chiral particles, and the Yukawa mass hierarchies. All of this is obtained from discrete symmetries and is unified at a single energy scale (Mgut).In summary, VACIA_Ω is a theoretical proposal that offers a unified, causality-consistent, and empirically testable solution to address Dark Energy and the hierarchy problem of fundamental forces.
