Cyberuniverse Matches Astronomical Observations in Fine Detail.

The article reports on the supercomputer simulation showing how dark matter, an invisible material of unknown composition, herded luminous matter in the universe from its smooth state into the web of galaxies and galaxy clusters that populate the universe developed by scientists at the University of Chicago in Chicago, Illinois. The Chicago researchers compared the results of its supercomputer simulations to the newest, most detailed astronomical observations available. Andrey Kravtsov, an associate professor of astronomy and astrophysics who predicted that galaxies of different luminosity or brightness clustered differently when the universe was young said that the distribution of galaxies in the Chicago team's cyberuniverse matched the real one.
