Bolshoi Simulation Visualization from UC-HPACC on Vimeo.

The Bolshoi Simulation, “the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made”.

What is actually being shown above is a visualization of dark matter in a small fraction of the actual simulation. Visit the Bolshoi website at the University of California High-Performance AstroComputing Center for more information and visuals.
