A New Simulation of the Universe is a map and a time machine combined into one.
Called Uchuu, which means “outer space” in Japanese, the map does not include Casseipoia or the moons of Neptune; instead, it’s a map of large-scale galaxies and galaxy clusters, all stuck together by an invisible network of black matter, which emits no electromagnetic radiation but still exerts a gravitational force on the universe.
Researchers from the University of Chiba in Japan, the Institute of Astrophysics of Andalusia in Spain and several other institutions in Europe, the United States, Argentina and Chile developed the simulation in order to study the structure of the universe over almost all of its 13.8 billion year history. .

The simulation is a virtual cube, 9.63 billion light years on each side, containing 2.1 trillion simulated dark matter particles. It was built on the ATERUI II supercomputer of the National Astronomical Observatory of Japan, and it took a year to set it up.
To produce Uchuu, “all 40,200 processors (processor cores) available [at the supercomputer] exclusively for 48 hours each month “, Tomoaki Ishiyama, computer scientist at Chiba University, said in a press release. “Twenty million supercomputer hours were consumed and 3 petabytes of data generated, the equivalent of 894,784,853 images from a 12-megapixel cell phone.”
Researchers reported the new simulation in the June issue of the journal Monthly notices from the Royal Astronomical Society.
“Uchuu is like a time machine,” said Julia F. Ereza, a doctoral student at the Institute of Astrophysics in Andalusia. “[W]We can move forward, backward and stop in time, we can “zoom in” on a single galaxy or “zoom in” to visualize an entire cluster, we can see what is really happening at every moment and at every place in the world. universe from its earliest days to the present day. ”
The card is available for download, or you can explore the new simulation even faster via a YouTube presentation.
