Dark Matter Movie from the Bolshoi Simulation:
The Bolshoi Cosmological Simulation allows us to simulate a flight through the universe seeing dark matter. This computer shows us what the beginning of the universe may have looked like because it shows different parts of dark matter such as a microwave background. Dark matter may contain normal galaxies or clusters of galaxies. The Bolshoi simulation is thought to be a reliable source of information because it is in agreement with the regular sky maps of today. The Bolshoi simulation supports the theories of dark matter but we still do not know the composition of dark matter or the nature of it. Scientists hope to use this simulation to explain how galaxies and other objects in the universe have changed since the Big Bang.
