A Model for Spherically Symmetric Matter Collapse, Black Holes and Wormholes

Abstract

We create programs that model the Einstein Field Equations for a massless scalar field in spherical symmetry. We recreate results shown by Garfinkle & Duncan (1998), specifically a scaling relation between the maximum scalar curvature at the centre of a collapsing region of matter that does not form an event horizon and the distance from initial configurations of matter that do form an event horizon. These programs can be modified in order to analyse the stability of wormholes.
