| contents | <p>This document provides a formal empirical analysis of the widening "tensions" within the standard <span class="math-inline">Lambda-</span>CDM cosmological model, specifically targeting the <span class="math-inline">H0</span> (expansion rate) and <span class="math-inline">S8</span> (structure growth) anomalies. Unlike multi-parameter extensions that introduce new particles or varying constants, this work proposes a <strong>Rank-1 Principal Mode</strong>—a single, anisotropic geometric deformation—as the unified source of late-time observational discrepancies.</p> |
