You are loading the Millenium Run, the largest n-body supercomputer simulation ever.

In a cube of space 2 billion light years wide, it traces the evolution of over 10 billion pieces of dark matter, each a billion times the mass of our sun, roughly equivalent to 20 million galaxies.

Our galaxy is a single point of light in this rendering.

Your view will span a billion cubic light-years of space -- unthinkably huge, but just a tiny part of the universe.

Please be patient while we load 5 million galaxies!
