Unified Description of the Casimir Force and Spacetime Curvature via the Emergent Effects of the Quantum Vacuum

This paper proposes a unified theory of gravity based on the emergent effects of quantum vacuum, whose core innovation lies in achieving cross-scale parameter closure from microscopic quantum effects to macroscopic gravitational phenomena.

The theory uses a set of microscopic parameters  independently calibrated from the Casimir effect to, for the first time, calculate Newtons constant G from first principles (with a 0.29% deviation from the experimental value) without introducing any dark components or extra degrees of freedom. It also self-consistently describes a series of cross-scale phenomena including surface gravity, the residual perihelion precession of Mercury, galactic rotation curves, dynamic dark energy, and the upper mass limit of neutron stars.
