Two Readings of One Geometry: The Lensing-Dynamics Discrepancy Solution

Why do gravitational lensing and galactic dynamics disagree? This work shows that light and matter read two distinct projections of the same underlying geometry. We derive a fixed number before comparing to data: 19/15 ≈ 1.267. KiDS, GAMA and HSC catalogues measure 1.2706 ± 0.0287. The same factor improves lensing fits — and degrades dynamical fits. No fitting. No free parameters. Full reproducibility scripts and data are included.

Abstract

Why do gravitational lensing and galactic dynamics disagree? This work shows that light and matter read two distinct projections of the same underlying geometry. We derive a fixed number before comparing to data: 19/15 ≈ 1.267. KiDS, GAMA and HSC catalogues measure 1.2706 ± 0.0287. The same factor improves lensing fits — and degrades dynamical fits. No fitting. No free parameters. Full reproducibility scripts and data are included.
