Gravity Energy Processing Bridge Jcost Zero Iff One

The cost of balance

In the Recognition Science framework, recognition, a discrete record of events, carries a forced cost. The cost function is J(x) = ½(x + 1/x) − 1 for positive x. The Jcost_zero_iff_one theorem proves that this cost is zero if and only if x equals 1. In plain language: the processing cost vanishes exactly at balance, where the input and its reciprocal match, and nowhere else.

The proof is a short chain of algebra. If J(x) equals zero, then x + 1/x equals 2, which rearranges to (x − 1)² = 0, forcing x = 1. The converse, that J(1) = 0, follows by direct substitution. The theorem is machine-checked in the framework's library of formal theorems, so the implication holds with no hidden assumptions beyond the definition of the cost function.

This zero-cost point is the anchor for the framework's energy model. The same library proves that near balance, writing x = 1 + ε, the cost equals ε²/(2(1 + ε)), which for small ε behaves like ε²/2. That quadratic form is the bridge to kinetic energy in weak fields: a small deviation from balance costs energy proportional to the square of the deviation, just as kinetic energy grows with the square of velocity. The framework models energy density as this processing cost, and any energy distribution with a nonzero gradient creates a processing field that can modify gravity.

The theorem does not claim that balance is achieved anywhere in the real universe, nor that the cost function itself is derived from physics. The form J(x) is forced by the framework's composition law, but the identification of that cost with physical energy is a modeling choice within the framework, not a proved fact about nature.

What this page does not claim

The theorem does not claim that any real energy distribution actually reaches the zero-cost balance point. The theorem does not derive the cost function J(x) from physical principles; the form is forced by the framework's composition law. The identification of processing cost with physical energy density is a modeling choice, not a proved fact.

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
