Theory 120 Zero: Emergent Gravity and Dynamic Dark Energy from Holographic Horizon Thermodynamics
Year: 2026
Type: report
Abstract: We propose Theory 120 Zero, a framework in which gravity and dark energy emerge from the thermodynamics of the cosmological horizon. Starting from the holographic principle, we derive Newton’s constant as an entropic elasticity $G \sim L_p^2 T_H$ and the Friedmann equations as thermodynamic identities applied to the Hubble horizon. The central result is a dynamic dark energy density originating from horizon curvature corrections. We obtain $\rho_{DE}(a) = \frac{3}{8\pi G} \left[ H_0^2 \Omega_{\Lambda 0} + \alpha H^4(a) \right]$, where the $H^4$ term arises naturally from the first quantum correction to horizon entropy $S = A/4L_p^2 + \alpha \ln(A/L_p^2)$. This predicts a time-varying equation of state $w(a)$ that deviates from $w=-1$ at high redshift, and provides a physical mechanism to address the cosmological constant problem without fine-tuning. We present testable predictions for $H(z)$, $f\sigma_8(z)$, and the CMB power spectrum, and outline how Theory 120 Zero can be falsified by upcoming surveys such as DESI, Euclid, and LSST. This work unifies gravity and cosmic acceleration under a single thermodynamic origin. Keywords: Holographic Principle, Entropic Gravity, Dark Energy, Cosmological Constant, H^4, Theory 120 Zero
