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 a substitute, it is a map of large-scale galaxies and galaxy clusters, all glued collectively by an invisible net of dark matter, which emits no electromagnetic radiation however nonetheless exerts a gravitational pressure upon the universe.
Researchers from Chiba University in Japan, the Institute of Astrophysics of Andalusia in Spain and a number of other different establishments in Europe, the United States, Argentina and Chile developed the simulation so as to examine the construction of the universe over virtually its total 13.8 billion-year historical past.
The simulation is a digital dice, 9.63 billion light-years on either side, containing 2.1 trillion simulated dark matter particles. It was constructed on the supercomputer ATERUI II on the National Astronomical Observatory of Japan, and took a yr to place collectively.
To produce Uchuu required “all 40,200 processors (CPU cores) accessible [at the supercomputer] completely for 48 hours every month,” Tomoaki Ishiyama, a pc scientist at Chiba University, said in a statement. “Twenty million supercomputer hours have been consumed, and three Petabytes of information have been generated, the equal of 894,784,853 footage from a 12-megapixel cellphone.”
The researchers reported the brand new simulation within the June difficulty 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 a complete cluster, we are able to see what is admittedly occurring at each immediate and in each place of the universe from its earliest days to the current.”
