Digital Cosmology Timeline

In the early 1980s, "scale-free" dark matter simulations were restricted to 2 dimensions and 250 zones or cells squared in order to limit the size of the computations. Using Convex C240 and Cray-2 supercomputers, Adrian Melott of the University of Kansas traced the gravitational clustering of dark matter in an expanding universe. The 2-D results portray the emergence of structure in a "slice" of the cosmos.
