The simulation spans a 12 billion light-year cube, uses 4.2 trillion dark matter particles, and required over 100 million CPU core-hours on Chinese supercomputers.
HyperMillennium enables researchers to study cosmic evolution, rare massive structures, and galaxy formation with unprecedented detail, supporting projects like the China Space Station Telescope and ESA's Euclid mission.
Praised by global experts, the simulation's data is now available to the scientific community, offering new opportunities for dark matter, dark energy, and cosmological model research.
