The Zuned Model: A Mass–Gravity–Time Coupled Mechanical Tensor Framework version 3

This paper introduces a novel gravitational framework that reinterprets spacetime as a physical "Mechanical Elastic Fabric." Moving away from purely geometric interpretations, the model establishes a fundamental coupling between mass, gravity, and a universal temporal deformation scale, denoted as \Delta t_0 = 1.05s. Key Contributions: Mechanical Field Equations: The framework proposes a modified stress-energy tensor T_{\mu\nu}^{(Z)} that accounts for fabric tension and energy distribution, providing a singularity-free alternative to classical black hole models. Precision Orbital Dynamics: The model is rigorously anchored to Solar System observations, precisely recovering the 43.03 arcsec/century perihelion precession of Mercury. Dynamic Gravitational Coupling: By introducing an effective coupling constant G_{eff} that depends on the temporal scale \Delta t_0 and cosmological time t_c, the model provides a mathematical pathway to explain early-universe galaxy formation and anomalies currently attributed to "Dark Matter". Nonlinear Strong-Field Extension: The inclusion of a nonlinear feedback parameter \lambda allows the model to remain physically consistent in extreme gravity regimes, preventing divergent behaviors and physical singularities.
