A brand new simulation of the universe is a map and a time machine rolled up into one.
Called Uchuu, which is Japanese for “Outer Space,” the map would not embody Casseipoia or the moons of Neptune; as an alternative, it is a map of large-scale galaxies and galaxy clusters, all glued collectively by an invisible web of dark matter, which emits no electromagnetic radiation however nonetheless exerts a gravitational drive upon the universe.
Researchers from Chiba University in Japan, the Institute of Astrophysics of Andalusia in Spain and a number of different establishments in Europe, the United States, Argentina and Chile developed the simulation in order to check the construction of the universe over virtually its whole 13.8 billion-year historical past.

The simulation is a digital dice, 9.63 billion light-years on all sides, containing 2.1 trillion simulated dark matter particles. It was constructed on the supercomputer ATERUI II at the National Astronomical Observatory of Japan, and took a yr to place collectively.
To produce Uchuu required “all 40,200 processors (CPU cores) out there [at the supercomputer] solely for 48 hours every month,” Tomoaki Ishiyama, a computer scientist at Chiba University, said in a statement. “Twenty million supercomputer hours have been consumed, and 3 Petabytes of knowledge have been generated, the equal of 894,784,853 photos from a 12-megapixel cellphone.”
The researchers reported the new simulation in the June issue of the journal Monthly Notices of the Royal Astronomical Society.
“Uchuu is sort of a time machine,” Institute of Astrophysics of Andalusia doctoral student Julia F. Ereza said in the statement. “[W]e can go ahead, backward and cease in time, we are able to ‘zoom in’ on a single galaxy or ‘zoom out’ to visualise an entire cluster, we are able to see what is absolutely occurring at each instantaneous and in each place of the universe from its earliest days to the current.”
The map is out there to obtain, or you may discover the new simulation even sooner by way of a YouTube introduction.
