Navigating The Dark Sector: Observational Constraints and Future Pathways for Post-ΛCDM Cosmology
Abstract
This document presents a comprehensive synthesis of the state of physical cosmology as of late 2025 and early 2026. It analyzes the observational evidence from Stage IV experiments (DESI, DES, Euclid) that challenge the standard ΛCDM model, highlighting the statistical preference for a dynamic dark energy and the persistence of tensions in H₀ and S₈.
