Abstract

The cosmological constant (CC, Λ\Lambda) problem represents a remarkable discrepancy of about 120 orders of magnitude between the observed dark energy and its natural expectation from quantum field theory. This paper synthesizes two paradigms - holographic naturalness (HN\mathcal{HN}) and pre-geometric gravity (PGG) - to propose a unified resolution. The HN\mathcal{HN} framework posits that CC stability is not a matter of radiative corrections but of quantum information and entropy. The large entropy SdSMP2/ΛS_\text{dS}\sim M_\text{P}^2/\Lambda of the de Sitter (dS) vacuum acts as an entropic barrier, exponentially suppressing destabilizing quantum transitions. This explains why the universe remains in a high-entropy, low-CC state. We embed this within PGG, where spacetime geometry and the Einstein-Hilbert action emerge dynamically from the spontaneous symmetry breaking SO(1,41,4)\rightarrowSO(1,31,3), driven by a Higgs-like field ϕA\phi^A. Both MPM_\text{P} and Λ\Lambda are generated from more fundamental parameters. Crucially, we establish a direct correspondence between the VEV vv of the pre-geometric Higgs field and the de Sitter entropy: SdSvS_\text{dS}\sim v (or v3v^3). Thus, the field generating spacetime also encodes its information content. The smallness of Λ\Lambda follows directly from the largeness of SdSS_\text{dS}, a manifestation of a large vv. The CC is stable because a large-entropy state's decay is exponentially suppressed. Our study shows new semi-classical quantum gravity effects dynamically generate "hairons", particles whose mass is tied to the CC. The instability of the dS space, driven by a condensate evolution, points to a dynamical origin for dark energy. This framework inextricably links the emergence of geometry, the hierarchy of scales and the quantum-information structure of spacetime, providing a novel path toward solving the CC problem.
