First full universe simulation zooms in on dark matter: ...the model covers 90 billion light years, which is the size of the universe that we are able to see, and follows 550 billion particles the mass of our Milky Way. This video starts with a large scale view of the distribution of dark matter in the cosmos today, which looks quite homogeneous. But as it zooms in, its structure becomes visible, showing clumps and filaments separated by expanses of void.
The simulation traces the evolution of dark matter as predicted by the standard model of cosmology, from the time the universe was in its infancy to the present. It mimics gravitational forces between all the clumps and the fact that they are moving in an expanding universe.
