A Holographic Information Estimate of the Cosmological Constant: A Phenomenological Approach
Year: 2026
Type: preprint
Abstract: The Cosmological Constant Problem—characterized by a large discrepancy between Quantum Field Theory (QFT) predictions and the observed dark energy density—remains a profound crisis in modern physics. In this paper, we present a phenomenological estimate based on the holographic information architecture of the universe. Using the standard Bekenstein-Hawking entropy bound [2,3], we calculate the maximum holographic bit count of the observable universe. We show that a bit-count phenomenological recasting of the Cohen-Kaplan-Nelson (CKN) bound [4] yields an effective vacuum energy density (rho_vac) of approximately 1.38 x 10^-10 J/m^3. We compare this theoretical estimate with the Planck 2018 best-fit observed dark energy density (rho_obs) of approximately 5.26 x 10^-10 J/m^3. The residual factor is resolved by a single-parameter framework. We calibrate a macroscopic dimensional-emergence scaling factor (alpha) to approximately 3.81, yielding a plausible factor-of-two range of 2.5 to 5.0. We emphasize that this is a self-consistency check rather than an independent derivation, providing a foundation for subsequent tests.
