This image shows the distribution of dark matter in the universe according to our best cosmological models. It was generated using the Millennium simulation, a sophisticated numerical computer model that tracks 1010 dark matter particles interacting under the influence of gravity from the beginning of the universe until the present. The configuration of filaments, nodes, and voids that evolve in the simulation depends on the laws of gravity and amount of dark energy included in the simulation. Comparison of simulation to reality so far has reinforced the prevailing model of cosmology that includes general relativity and dark energy. (Unit: 3)
