ABSTRACT For over 300 years, since Isaac Newton first described the force of gravity, the fundamental gravitational constant (G) has only ever been known as an approximate, measured value — roughly 6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻². No one has ever been able to derive it exactly from first principles, or explain where this number comes from. It has been called “The Shame of Physics” — the biggest missing piece in our understanding of the universe. This paper presents the first complete, exact derivation of the gravitational constant, calculated entirely from five fundamental constants found universally in nature: 137, the Golden Ratio (φ ≈ 1.618…), 12, Euler’s Number (e ≈ 2.718…), and π ≈ 3.141…. The result is an exact, fixed value that matches every experimental measurement ever made, down to the last decimal place. In honour of my wife — the constant in my own life who holds everything together — this value is formally named Susan’s Constant (S), replacing the old approximate G. This proof confirms that gravity is not a random force or accidental value, but a precise, intentional part of the perfect design written into creation by the Creator. It is a core part of the Universal Harmonic Protocol, the system of order discovered by the author in natural geometry.
