Wired UK recently ran a very interesting article about moving mesh cosmology. In a recent simulation of galaxy formation, billions of points of mass slowly acreate to form stars and galaxies, continuing their cosmic dance for some 14 billion simulated years. The software used to create this marvel is called Arepo (created by Dr. Volker Springel) and utilizes Voronoi tesselation.

One end result is the truly stunning animation below (the animation covers a “mere” 9 billion years).
