Conformal theory of galactic halos

In current cosmology, an observed galaxy is considered to be surrounded by a large spherical halo attributed to dark matter. Galaxy formation by condensation of mass-energy necessarily depletes the original uniform cosmic background. This must leave a scar, in the form of a gravitational field halo, as observed in anomalous galactic rotation and in gravitational lensing. Without invoking dark matter, conformal theory accounts for the otherwise counterintuitive centripetal effect.
