Description

I present a relativistic modified gravity theory based on a scalar function of the torsion tensor. In the weak-field limit, the field equations naturally reduce to the deep-MOND regime without introducing dark matter. This framework simultaneously reproduces the observed deflection of light across individual galaxies and clusters, and yields an exact derivation of the baryonic Tully-Fisher relation. These results suggest that torsional degrees of freedom offer a viable, covariant completion of MOND that passes critical gravitational lensing tests.
