Entropy-Stabilized Suppression of Vacuum Energy: A TEQ-Based Structural Mechanism

The discrepancy between the vacuum energy predicted by quantum field theory and the observed cosmological constant is often cited as the most severe fine-tuning problem in physics, with theoretical estimates exceeding observational bounds by up to 120 orders of magnitude. Here, we present a structural mechanism within the Total Entropic Quantity (TEQ) framework that suppresses vacuum energy without fine-tuning. TEQ introduces entropy geometry and resolution stability as first principles, filtering out unresolved quantum fluctuations that do not contribute to distinguishable structure. We define a simple entropy curvature functional g, apply it to the vacuum energy integral, and show that the resulting entropy-weighted suppression leads to a finite, scale-dependent energy density. When the entropic resolution parameter β is set by cosmological considerations, such as the Hubble horizon, the predicted value aligns with observation. Rather than regularizing divergences, TEQ reinterprets the vacuum sum through a structural criterion of resolvability, offering a conceptually grounded and observationally consistent perspective on the cosmological constant problem.
