Singularity-free black holes in Conformal Gravity |
|
Abstract |
We explicitly show that Weyl conformal symmetry solves the black hole singularity problem, otherwise unavoidable in a generally covariant local or non-local gravitational theories. Following the seminal paper by Narlikar and Kembhavi, we provide examples of syngularity-free (spherically symmetric and axi-symmetric) exact solutions for black hole spacetimes in conformal gravity. We check the absence of divergences making use of the Kretschmann-invariant and we show that the new types of black holes are geodesically complete. Indeed, no massive or massless particles can reach the former singularity in a finite amount of proper time or of affine parameter. |
