Vacuum Noise, Decoherence, and Fluctuations in rCVGT

This paper presents a physical theory of vacuum noise and decoherence within the framework of Relativistic Coherent Vacuum Gravity Theory (rCVGT). The work addresses the conceptual limitations of standard quantum field theory, where vacuum fluctuations are typically described in terms of operator uncertainties and decoherence is modeled through environmental entanglement without a direct physical description of vacuum dynamics. In rCVGT the vacuum is treated as a structured relativistic medium characterized by a coherence order parameter ψ (x), a coherence magnitude Q (x) =|ψ (x) |², a vacuum-flow four-field u^μ (x), and a physical time-rate field τ (x). Vacuum fluctuations are interpreted as dynamical perturbations of these fields around metastable equilibrium states. The theory provides a physical mechanism for vacuum noise and shows how decoherence can arise from irreversible amplification of coherence fluctuations through coupling to macroscopic systems. Within this framework, vacuum noise, decoherence, and the quantum-to-classical transition obtain a unified physical interpretation while preserving the empirical predictions of quantum mechanics. This work contributes to the ongoing development of rCVGT as a physically motivated extension of relativistic vacuum dynamics and provides a foundation for future theoretical and experimental investigations of vacuum structure and coherence phenomena.
