Equazione fondamentale dimostrazione

This work introduces the Universal Equation, a fundamental variational principle proposed as the basis of a final unified theory of physics.From this single equation, Schrödinger, Einstein, and Dirac equations emerge naturally as special cases.The framework also resolves nineteen of the most significant open problems in modern physics, including dark matter, dark energy, the arrow of time, and the removal of singularities. A key falsifiable prediction is the existence of gravitational wave echoes with a characteristic timescale of ~50 ms, within the detection range of LIGO, Virgo, and KAGRA. Unlike string theory or loop quantum gravity, the Universal Equation is minimal, universal, and directly testable.This preprint represents a step toward a compact, falsifiable, and experimentally relevant theory of everything.
