Non-Equilibrium Triple Coincidence (Unified BH Framework)

Experiment V2.78: Non-Equilibrium Triple Coincidence (Unified BH Framework)

Status: COMPLETE

Goal

Extend the non-equilibrium triple coincidence test to a unified framework covering all horizon types: static black holes (Schwarzschild, Kerr, Reissner-Nordstrom), dynamical black holes (Vaidya, generalized Vaidya), FRW cosmology, and local Rindler.

Evaluate 9 theories across 27 test scenes spanning 4 geometry regimes.

Key Results

GR achieves perfect thermodynamic equilibrium (L_total = 0) while modified gravity theories exhibit non-zero theory-excess entropy production.

Regime Analysis

Static Black Holes

All theories pass static BH equilibrium. Static configurations have no heat flux and no entropy change, so the Clausius relation is trivially satisfied.

Dynamical Black Holes (Vaidya)

Strongest discrimination regime:

TheoryBH Dynamical LossEquilibrium?
GR0.0YES
Starobinsky1.0e-16YES
BD-Solar4.0e-6YES
f(R)-Weak0.01NO
f(R)-Strong1.0NO
BD-Extreme816.3NO
4D-EGB100.0NO

FRW Cosmology

Similar discrimination pattern. GR at equilibrium, all modified theories with significant deviations fail.

Local Rindler

All theories pass. Local Rindler patches test entanglement equilibrium, which is less sensitive to theory modifications than dynamical horizons.

Physical Conclusions

  1. GR Uniqueness: GR is the unique theory (among those tested) that achieves perfect thermodynamic equilibrium across all horizon types and dynamical regimes.

  2. Observational Viability Correlation: Theories that pass solar system and cosmological tests also achieve near-equilibrium, suggesting a deep connection between thermodynamic equilibrium and observational viability.

  3. Scaling Laws:

    • f(R): L proportional to alpha^2
    • BD: L proportional to 1/omega^2
    • 4D-EGB: L proportional to alpha_GB^2

Integration Validation

Tolman Redshift

The Tolman relation T_local = T_H / sqrt(f(r)) validated at 5 radii to machine precision (relative error < 10^{-15}).
