Unattainable extended spacetime regions in conformal gravity

Abstract The Janis-Newman-Winicour metric is a solution of Einstein’s gravity minimally coupled to a real massless scalar field. The γ-metric is instead a vacuum solution of Einstein’s gravity. Both spacetimes have no horizon and possess a naked singularity at a finite value of the radial coordinate...
