Gravity Black Hole Entropy From Ledger C Rs Neq String

The leading-log coefficient

Black holes carry entropy, a measure of the number of microscopic states they can hold. The Bekenstein-Hawking formula gives the leading term: entropy equals one quarter of the horizon area in Planck units. For decades, physicists have asked what happens when quantum gravity corrections are added. The standard answer is a logarithmic correction: the entropy becomes A/4 plus a coefficient times the logarithm of the area. Different approaches to quantum gravity predict different values for that coefficient.

Loop quantum gravity predicts -1/2, and string theory predicts -3/2. The Recognition Science framework, which builds physics from a discrete ledger of recognition events, derives its own value: c_RS = -log(φ)/2, where φ is the golden ratio, approximately 1.618. This is about -0.241, a number clearly different from both rivals. The declaration c_RS_neq_string is a machine-checked theorem stating that c_RS is not equal to -3/2. The proof is short: if the two were equal, then log(φ) would equal 3, but the framework's library has already proved that log(φ) is less than 1. A companion theorem, c_RS_neq_LQG, proves the same distinction from -1/2.

In Recognition Science, the ledger is a discrete record of recognition events, and the entropy of a black hole horizon is counted as admissible states modulo an equivalence. The framework's library, a machine-checked collection of formal theorems, proves the leading term matches the Bekenstein-Hawking value exactly. It also proves the leading-log coefficient is negative and φ-rational, and that it differs from both canonical predictions. These are algebraic facts about the framework's definitions, established with no unproved assumptions beyond the standard logical axioms.

The theorem does not claim that the framework's value is the correct one. The empirical question, which coefficient nature actually uses, remains open. The framework states a falsifier: independent observation or computation of the leading-log coefficient that falls outside the interval (c_RS - 0.05, c_RS + 0.05) would refute the prediction. The algebraic structure is proved; the physical match is a hypothesis awaiting adjudication by semiclassical gravity.

What this page does not claim

The theorem does not claim that the Recognition Science value of the leading-log coefficient is the empirically correct one. The theorem does not claim that the framework's derivation of black-hole entropy from a discrete ledger is physically realized. The theorem does not claim that the leading-log coefficient is the only distinguishing prediction between the frameworks.
