The Millenium Simulation

The Millenium simulation is the largest simulation of the formation of structures ever made. Ten billion objects were modelled in their gravitational interaction. Each of the objects represents a lump of dark matter with a mass of a billion sun masses. The initial data for the simulation were taken from the obserations of the WMAP satellite.

The enormous size of the simulation makes visible the geometric richness of structures on various length scales. On the largest scale with several billion lightyears the universe seems to be homogeneous. With an increase of the zoom sequence we see the filament structure of the dark matter. The zoom finishes with a galaxy cluster, consisting of many thousand galaxies.

The astronomical unit of 1 Parsec (pc) corresponds to 3.26 light years.
