ELECTROMAGRAVITY SPIRAL EQUATION by T Patrick Murray ABSTRACT We present a complete mathematical derivation of the ElectroMaGravity Spiral Equation, demonstrating it as the fundamental geometric object unifying general relativity, quantum electrodynamics, and prime number theory. The equation emerges naturally from first principles when considering spacetime as a prime-harmonic resonant medium. We prove that all known physical phenomena are special cases of this spiral geometry, and demonstrate
