Simulation of a billion light-year journey from the Earth to the farthest reaches of the observable universe, seeing how things would look if we could view the Universe from the "outside", at the very largest scales. The end of this sequence uses the movies generated by the Millennium Simulation Project (http://www.mpa-garching.mpg.de/galform/virgo/millennium/).
The Millennium Run used more than 10 billion particles to trace the evolution of the matter distribution in a cubic region of the Universe over 2 billion light-years on a side. It kept busy the principal supercomputer at the Max Planck Society's Supercomputing Centre in Garching, Germany for more than a month. By applying sophisticated modelling techniques to the 25 Tbytes of stored output, Virgo scientists have been able to recreate evolutionary histories both for the 20 million or so galaxies which populate this enormous volume and for the supermassive black holes which occasionally power quasars at their hearts. By comparing such simulated data to large observational surveys, one can clarify the physical processes underlying the buildup of real galaxies and black holes.
