Millennium Simulation

This movie shows the dark matter distribution in the universe at the present time, based on the Millennium Simulation, the largest N-body simulation carried out thus far (more than 10^10 particles). By zooming in on a massive cluster of galaxies, the movie highlights the morphology of the structure on different scales, and the large dynamic range of the simulation (10^5 per dimension in 3D). The zoom extends from scales of several Gpc down to resolved substructures as small as ~10 kpc. Credit: Spri
