A massive simulation of the cosmos and a nod to the next generation of computing
A team of physicists and computer scientists from the U.S. Department of Energy s (DOE) Argonne National Laboratory performed one of the five largest cosmological simulations ever. Data from the simulation will inform sky maps to aid leading large-scale cosmological experiments.
The simulation, called the Last Journey, follows the distribution of mass across the universe over time in other words, how gravity causes a mysterious invisible substance called dark matter to clump together to form larger-scale structures called halos, within which galaxies form and evolve.
