RGMEC Version 2.0: Relative Gravitational Matter–Energy Confinement — Temporal Dynamics as an Emergent Property of Gravitational Confinement

RGMEC Version 2.0 (Relative Gravitational Matter–Energy Confinement) presents a structural interpretation of gravitational time dilation that remains mathematically identical to the Schwarzschild solution of General Relativity. The framework introduces no new gravitational field, force, or free parameters, and does not modify Einstein’s equations. Instead, it interprets gravitational time dilation as an emergent manifestation of the organization and confinement of matter and energy within gravitational systems. The manuscript develops this interpretation, compares it directly with General Relativity, and evaluates its consistency using observational audits spanning Earth gravity, GPS, laboratory redshift experiments, white dwarfs, neutron stars, and black-hole horizons. The work is intended as a complementary physical interpretation rather than an alternative theory of gravity.
