Abstract

A dynamic model of gravitational interaction was proposed earlier which results in a velocity-dependent drag. This drag can quantitatively explain the cosmological red shift in a stationary universe, the secular acceleration of Phobos, the secular retardation of the Earth's rotation without any problem of the controversial close approach of the Moon and the extra red shift at the solar limb. In the present paper it has been shown that such a velocity dependent inertial induction can act as a servomechanism for distributing matter in rotating spiral galaxies in such a way that flat rotation curves are obtained. A truncated thin disc model has been assumed, but the results are strongly in favour of the proposition.
