Spiralicity and Motion on Cosmic Scale
  We hypothesize a simple scenario to associate spiral-shaped trajectories and
asymptotic tangential velocities according to observations found on deep space
scales. As a difference with alternative Modified Newton Dynamics (MoND), in
our scenario the dynamics at cosmic distances depends on the velocity of the
rotating galaxy instead of its acceleration. We assume dark matter to exert a
quadratic fluid resistance force with an added non-linear drag force in the
radial direction.
