A Little Quantum Help for Cosmic Censorship and a Step Beyond All That

Advances in High Energy Physics, 2013
The hypothesis of cosmic censorship (CCH) plays a crucial role in classical general relativity, namely, to ensure that naked singularities would never emerge, since it predicts that whenever a singularity is formed an event horizon would always develop ...

String Theory Explanation of Galactic Rotation Found Using the Geodesic Constraint

Advances in High Energy Physics, 2019
The unique spherically symmetric metric which has vanishing Weyl tensor, is asymptotically de-Sitter, and can model constant galactic rotation curves is presented. Two types of field equations are shown to have this metric as an exact solution. The first
