Even though such a negative curvature (a curvature which a galactic rest frame observer recognizes as a universal linear potential which gives rise to a universal acceleration) is only achievable in standard gravity by extreme fine tuning, nonetheless, it is naturally realizable in conformal gravity, a currently viable, fully covariant, candidate alternate gravitational theory.LaTeX, 4 pages.
