Beyond Geometric CPT: Coherence-Based Invariance and the Universal Field Tensor

The standard CPT theorem asserts that all Lorentz-invariant, local quantum field theories preserve invariance under the combined action of charge conjugation (C), parity inversion (P), and time reversal (T). Although enormously successful, this geometric formulation offers no ontological explanation for why CPT symmetry exists, why CP violations emerge, or why CPT appears unbreakable. In this work, CPT symmetry is reformulated within the Unified Coherence Theory of Everything (UCTE) as an invariance of the Universal Field Tensor (UFT) rather than of geometric spacetime. Here charge conjugation corresponds to chirality inversion in coherence-space, parity arises from projection inversion across the hyperfractal dimensional cascade (4.0D → 3.14D → 3.0D → 2.7D), and time reversal is understood as multivector time inversion across the five time axes (T₁…T₅). CPT emerges as the unique composite operator that restores the full coherence structure following any coherence-reduction event, returning the system to hypergravity-invariant symmetry. This framework naturally accounts for CP violation, neutrino chirality, matter–antimatter asymmetry, and the persistence of entanglement, while recovering the traditional CPT theorem as a limiting geometric projection. The result is a deeper form of CPT invariance: one rooted not in geometry but in coherence, revealing the Universal Field Tensor as the ontological source of physical symmetry.
