Overview

Monograph demonstrates a geometric theory explaining galaxy rotation, suggesting implications for gravitational dynamics.

Key Points

  • The aim is to investigate if observed deviations in galactic motion can arise from geometric responses rather than unaccounted forces or matter.
  • Implemented Geometric Theory of Gravity 3.5 on 30 bulgeless SPARC galaxies with 504 rotation-curve points.
  • Performed calculations using a fixed acceleration scale and detailed baryonic source models without galaxy-dependent parameters.
  • Assessed model performance via RMSE comparisons with baryonic Newtonian models and algebraic RAR benchmarks.
  • GTG 3.5 achieved an RMSE of 20.670 km/s, outperforming the baryonic Newtonian model in 29 out of 30 galaxies.
  • The holdout sample produced an RMSE of 18.620 km/s, better than the baryonic Newtonian model in 14 out of 15 galaxies.
  • Observations indicated a nearly zero signed velocity bias, indicating no systematic prediction issues in the tested population.
