We assume that the individual stars which are located at the peripheral parts of the spiral galaxies are experiencing a drag force acting upon them radially. Such a force might be produced by some sort of a dynamically generated viscous medium, and as the stars are in the state of free fall toward the center of the galaxy, then it would balance the centripetal force acting on the star, thus resulting in a terminal velocity. We make no attempt to explain the origin of the assumed drag force or show how it could be generated, but we have tried to test such an assumption by fitting the calculated velocity curves of 18 spiral galaxies with rotation curves obtained from actual observations. Results show remarkable agreements.
