Hydrodynamic Model of Gravity as Manifestation of Quantum Vacuum Energy Exchange

This work investigates the possibility of describing gravitational interaction within the framework of a hydrodynamic model of the quantum vacuum. Nucleons are modeled as toroidal vortices absorbing vacuum energy, leading to a pressure gradient identified with gravity. The model qualitatively agrees with the law of universal gravitation and offers a path toward unification with electromagnetic phenomena. The justification relies on classical ideas of Sakharov's induced gravity (1967) and modern analog models of gravity in hydrodynamics, including the superfluid vacuum theory.
