Systems involving strongly curved spacetimes, especially the vicinities of compact objects (black holes and neutron stars), must be modeled using the general theory of relativity. Except in special, high-symmetry cases, this requires numerical simulation. The four-dimensional theory must be "split" into a three-dimensional system evolved through time; coordinate choices must be made and their effects separated from physically meaningful dynamics; physical singularities must be treated in a numerically stable way. If we can do this, we can simulate the merger of compact binary systems and make predictions about gravitational waves and gamma ray bursts.
