A groundbreaking demonstration that Newton’s gravitational constant G can be derived from first principles—no empirical inputs—within a novel Phase Wave Determinism framework. By enforcing global phase quantization and conformal consistency, we fix the vacuum scalar ϕ0 and nonminimal coupling ξ=1/6\xi=1/6ξ=1/6, yielding Gtheory=6.6743×10−11. This self-contained approach also resolves longstanding issues—from wave-function collapse and entanglement paradoxes to black-hole singularities and quantum gravity unification—marking a true paradigm shift.
