Abstract
We have constructed a new computer code to solve Einstein's equations of general relativity for the dynamical evolution of a relativistic star cluster. The cluster may contain a large number of stars that move in a strong gravitational field at velocities approaching the speed of light. Unstable star clusters undergo catastrophic collapse to black holes. The collapse of an unstable cluster to a supermassive black hole at the center of a galaxy may explain the origin of quasars and active galactic nuclei. By means of a supercomputer simulation and color graphics, the whole process can be viewed in real time on a movie screen.We have also written a multidimensional, relativistic hydrodynamics code to determine the flow of gas onto such black holes. This problem has defied solution for 45 years. Even the generation of gravitational waves can now be calculated on a supercomputer. Longstanding theoretical questions such as the validity of the Cosmic Censorship Hypothesis and the Hoop Conjecture may soon be settled by numerical simulations.
