90 Billion Light Years –Evolution of Dark Matter in the Observable Universe (Video)




Jean-Michel Alimi from the French National Centre for Scientific Research (CNRS) and colleagues from the DEUS consortium, created a model of the evolution of dark mattter that 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.

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.

"These simulations concern only gravity and dark matter," says Pier-Stefano Corasaniti, a member of the team. "But I think the performance of the algorithms are becoming efficient enough to run simulations that include baryonic gas or dark energy fluid itself."
