Blog - Largest-Ever Simulation of the Universe Revealed

Blog - Largest-Ever Simulation of the Universe Revealed: ...These guys have carried out the largest simulation of the universe ever undertaken, consisting of 374 billion particles in a box some 10 gigaparsecs across. That's roughly equivalent to about two thirds the size of the observable universe...

The purpose of the simulation is to reproduce the entire evolution of a universe made largely of cold dark matter to see whether it produces same structures that we see in ours--from the galactic structures to galactic clusters, galactic superclusters and beyond.

The most recent theories predict that our universe ought to have structures on the very largest scales called acoustic baryon oscillations. These are essentially the leftovers of waves in the plasma that existed in the very early universe which became frozen in place as they cooled.
