Abstract: We show that it is not at all neccesary to assume the validity of the standard Newton-Einstein gravitational theory in order to account for gravitational phenomenology on solar system distance scales. Rather, we show the standard theory to only be sufficient, with its extrapolation to much larger distance scales such as galactic being, for the moment, just that, and with it being precisely this very extrapolation which leads to the dark matter fix. Additionally, we present an alternate covariant gravitational gravity, viz. conformal gravity, one which has a very different such galactic extrapolation, one which then enables us to explain galactic rotation curve systematics without needing to appeal to dark matter at all. Additionally, we show that these same galactic rotation curves possess an explicit imprint on them due to the global cosmological Hubble flow, and identify it as a possible manifestation of Mach's principle.
