Inside The Largest Simulation Of The Universe Ever Created | Popular Science

Simulating Matter Distribution Across The Cosmos Joe Insley and the HACC team, Argonne National Laboratory.

Sometime next month, the world’s third-fastest supercomputer —known as Mira—will complete tests of its new upgraded software and begin running the largest cosmological simulations ever performed at Argonne National Laboratory. These simulations are massive, taking in huge amounts of data from the latest generation of high-fidelity sky surveys and crunching it into models of the universe that are larger, higher-resolution, and more statistically accurate than any that have come before. When it’s done, scientists should have some amazing high-quality visualizations of the so-called “cosmic web” that connects the universe as we understand it. And they’ll have the best statistical models of the cosmos that cosmologists have ever seen.
