Rotation velocity predicted in the D–M universe for a point mass located at r = 0 and surrounded by a depletion zone and the same mass of antimatter (with opposite “sign”). Instead of the expected Newtonian velocity (see Eq. (11)), decreasing to zero, D–M predicts that the rotation velocity for a condensed object of positive mass will be nearly constant (see Eq. (14)) above the characteristic distance approximately equal to half the radius r_d of the depletion zone, or ≈3 virial radii.
