Do time delay effects explain galactic velocity profiles?

Year: 2026

Type: preprint

Abstract: Using the gravitoelectromagnetic analogy for weak gravitational fields, we critique explanations of galactic velocity profiles that invoke time delay effects (i.e. "retarded gravity"). For isotropic, time-dependent matter currents, we show within this framework that the force exerted on an orbiting body is Newtonian and due only to the instantaneous ambient matter configuration -- there are no time delay effects in such situations.
