Building the Universe Inside a Supercomputer

by Ian O'Neill at Discovery News.

In an arXiv preprint publication submitted on Dec. 8, Juhan Kim and colleagues from the Korea Institute for Advanced Study in Seoul have completed the largest simulation of the universe ever attempted.

The simulation calculates the evolution of 374 billion cold dark matter particles in a box some 10 gigaparsecs across—this represents approximately two thirds the size of the observable Universe. This virtual universe is 8,800 times larger than the previous record holder.
