Mass is redefined as a Curvature-Driven Emergence. The Higgs mechanism and Yukawa couplings are obsolete. We present the Modified Einstein Spherical (MES) Universe Model, a closed quasi-static spacetime framework where mass and light originate entirely from pure geometric curvature, inverting the causality of general relativity. By introducing three scalar-field corrections—Zaitian Quantum Power (Zjk), Nonlinear Symmetry (Njk), and Chaotic Power (Cjk)—to Einstein’s equation, we unify mass generation, photon behavior, and dark sector phenomena without invoking the Higgs mechanism or cosmic expansion. This MES Universe Model posits a left-hand rotating, quasi-static Yin-Yang Tai Chi Sphere geometry, where matter-antimatter equilibrium and quantum entanglement are geometrically enforced. We derive testable predictions, including photon frequency modulation (∆v/v ~ 10-15), enhanced Bell violations (SMES≈3.11), and gravitational wave dispersion, while addressing conflicts with the Standard Model and ΛCDM cosmology. This MES framework offers a bold, falsifiable synthesis of quantum mechanics and cosmology, pending rigorous experimental validation. By framing mass, light, time, and entanglement as emergence from spacetime curvature, it proposes a unified framework unlike any mainstream model today.
