We conclude that these black hole alternatives having $r_0$ below this maximum range (i. e. $r_0\leq r_{0, max}$) is consistent with the size and deviation from circularity of the observed shadow of M87$^{*}$.

The approach to incorporate quantum effects in gravity by replacing free particle geodesics with Bohmian non-geodesic trajectories has an equivalent description in terms of a conformally related geometry, where the motion is force free, with the quantum effects inside the conformal factor, i. e., in the geometry itself.
