Millennium

The Millennium Simulation is one of several projects to predict the evolution of universe by inputing large amounts of data. What makes Millennium different from the others is the shear size of the simulation. Using over 10 billion particles over a cubic region of space 2 billion light year on a side, the Millennium Simulation has successfully modeled the evolution of this large part of the universe from only 400,ooo years after its beginning till the present. The 25 terabytes of information on the 20 million galaxies, which held up an entire super computer center for a month, has cleared up several perceived difficulties with the modern view of the universe already and many more discoveries are expected.
