Gravity as an Emergent Phenomenon of Irreversible Quantum Decoherence: A Heuristic Solution to the Vacuum Energy Catastrophe

This paper proposes a theoretical hypothesis where gravitational interaction is treated not as a fundamental force dependent solely on mass-energy density, but as an emergent phenomenon derived from the density of irreversible wavefunction collapses (quantum decoherence). Challenging the standard causality of Objective Reduction models, a causal inversion is suggested: the fixation of information via decoherence and the consequent increase in information entropy induce spacetime curvature. Under this framework, the quantum vacuum—characterized by reversible virtual fluctuations lacking causal memory—becomes gravitationally inert. This mechanism acts as an "irreversibility filter, " offering a potential solution to the Cosmological Constant Problem by reconciling the high energy density predicted by Quantum Field Theory with the low curvature observed in the universe. Preliminary heuristic analysis suggests that if the information generation rate corresponds to the Compton frequency of matter, the coupling constant required to recover standard Newtonian gravity is of the order of unity (1).
