Researchers have constructed a virtual universe and released the software, known as Uchuu, to the public via the cloud. The software is billed as the largest and most realistic simulation of the universe to date. Uchuu is the Japanese term for ‘outer space. In a computational cube measuring 9.63 billion light-years across, there are 2.1 trillion particles in the simulation.
The project’s creators claim that their product is the most accurate and expansive universe simulation ever produced. The distance between Earth and the most distant galaxies we can observe is around 75 percent of the distance between Earth and the most distant galaxies we can observe. Uchuu was constructed by the team in order to investigate the universe on a scale that had never been conceivable before.
Uchuu, which focuses on the universe’s large-scale structure, contains dark matter halos that are currently unknown. Individual stars and planets are not found inside the software’s vast scale, thus anyone examining it will be disappointed. That means there will be no fascinating extraterrestrial worlds to explore.
Uchuu was created to create the illusion of the cosmos over about 13.8 billion years, beginning with the Big Bang and ending in the present day. Julia F. Ereza, a researcher, utilizes the software to analyze the formation of the universe, remarking that the time domain effectively builds a time machine. Users can travel through time, zoom in on a single galaxy, or enjoy a broader view of an entire galaxy cluster.
The ATERUI II supercomputer and all of its 40,200 CPU cores are required for the building of Uchuu. The simulation used all of the power from those cores for 48 hours per month for a total of 20 million supercomputer hours. Researchers generated 3 petabytes of data while developing the software. Simulation, on the other hand, can be compressed to 100 terabytes using compression techniques.
