Query: From Black Holes to Cosmology : The Universe in the Computer   I discuss some aspects of the use of computers in Relativity, Astrophysics
and Cosmology. For each section I provide two examples representative of the
field, including gravitational collapse, black hole imagery, supernovae
explosions, star-black hole tidal interactions, N-body cosmological simulations
and detection of cosmic topology.
