World's Fastest Supercomputer Created Largest Ever Universe Simulation

Using Frontier, the fastest supercomputer in the world hosted at Oak Ridge National Laboratory, researchers at the Department of Energy's Argonne National Laboratory in the US carried out the largest simulation of the universe ever produced.

The project's results, known as ExaSky, will assist astrophysicists and cosmologists in understanding the evolution and physics of the universe, including exploring the enigmatic nature of dark matter. By comparing these simulations with real-world observations, scientists aim to uncover the fundamental properties that govern the universe's long-term behavior.

What you see in this video released by the team is a small sample from the Frontier simulation, depicting the evolution of the expanding universe in a region with a massive galaxy cluster. The left side illustrates the cluster's development from billions of years ago to the present day, with red areas indicating hotter gases, reaching temperatures of over 100 million Kelvin. On the right, star tracer particles reveal the formation and movement of galaxies over time.

This massive galaxy cluster is forming within 311,296 cubic megaparsecs and represents just 0.001% of the entire simulation's volume, hinting at even more astonishing results in the future.
