Evaluating Physically Motivated Ultraviolet Cutoff Scales in the Cosmological Constant Problem
Year: 2026
Type: preprint
Abstract: This paper investigates the cosmological constant problem by examining how changing the quantum energy cutoff scale impacts predicted vacuum energy density. By comparing theoretical field calculations across major physics boundaries against astronomical observations of dark energy, the study demonstrates that lowering the energy scale significantly reduces the theoretical gap. However, a substantial residual discrepancy remains, proving that modifying momentum boundaries alone cannot resolve the issue and that additional physical mechanisms are required.
