Dark Energy and Extending the Geodesic Equations of Motion: A Spectrum of Galactic Rotation Curves

Achilles D. Speliotopoulos

A recently proposed extension of the geodesic equations of motion, where the worldline traced by a test particle now depends on the scalar curvature, is used to study the formation…
