The accelerating expansion of the Universe is reframed as the resolution to a gravitational analogue of Olbers' Paradox. Because gravitational influence propagates at the speed of light—confirmed by the binary neutron star merger GW170817—each observer is surrounded by a cosmological event horizon beyond which matter exerts no gravitational pull. The horizon is a thermodynamic object: it possesses a temperature proportional to the Hubble parameter and an entropy proportional to its area. As the universe expands, the horizon grows and its entropy S_H ∝ R²_H increases geometrically — present in any expanding spacetime regardless of matter content. The second law of thermodynamics drives the universe toward states of larger horizon radius. The resulting entropic pressure, P = −(2/3)ρ_crit c², yields an effective equation of state ω_eff = −2/3, providing accelerating expansion with no vacuum energy contribution and dissolving the cosmological constant problem without fine-tuning. The predicted dynamical dark energy, with ω ≠ −1 evolving with redshift, is consistent with the 4.2σ deviation from ΛCDM reported by the DESI Year 3 (DR2) survey.
