Germany / United States Metacomputing the Einstein Theory of Spacetime: Colliding Black Holes and Neutron Stars Across the Atlantic Ocean iGrid SC ’98 This simulation of the complete set of 3D Einstein equations of general relativity, performed using a new parallel computer code called “Cactus,” enables astrophysicists to study colliding black holes, neutron stars, the formation of singularities, and other aspects of Einstein’s theory that cannot be handled by analytic means.
