Our most successful theory of gravitation, general relativity, constitutes a complicated system set of nonlinear partial differential equations. For such systems finding exact analytic solutions in all but the simplest scenarios is hopeless. The only method we have to reach extreme parts of the solution space therefore is to use numerical methods. In my talk I will describe this approach, known as numerical relativity, and give an overview of some open problems, focusing especially on examples with naked singularities.
Short bio: David Hilditch works on extreme spacetimes in general relativity. He is an FCT investigator based within the CENTRA research unit at Instituto Superior Tecnico, where he will soon take up a position as assistant Professor. Earlier he was a postdoctoral researcher at the University of Jena in Germany. David wrote his PhD at the University of Southampton in the UK.
