A brand new simulation of the universe is a map and a time machine rolled up into one.
Referred to as Uchuu, which is Japanese for “Outer House,” the map does 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 internet of darkish matter, which emits no electromagnetic radiation however nonetheless exerts a gravitational power upon the universe.
Researchers from Chiba College in Japan, the Institute of Astrophysics of Andalusia in Spain and several other different establishments in Europe, the US, Argentina and Chile developed the simulation with a purpose to research the construction of the universe over virtually its complete 13.8 billion-year historical past.

The simulation is a digital dice, 9.63 billion light-years on both sides, containing 2.1 trillion simulated darkish matter particles. It was constructed on the supercomputer ATERUI II on the Nationwide Astronomical Observatory of Japan, and took a yr to place collectively.
To supply Uchuu required “all 40,200 processors (CPU cores) obtainable [at the supercomputer] completely for 48 hours every month,” Tomoaki Ishiyama, a pc scientist at Chiba College, mentioned in an announcement. “Twenty million supercomputer hours have been consumed, and three Petabytes of knowledge have been generated, the equal of 894,784,853 photos from a 12-megapixel cellphone.”
The researchers reported the brand new simulation within the June problem of the journal Month-to-month Notices of the Royal Astronomical Society.
“Uchuu is sort of a time machine,” Institute of Astrophysics of Andalusia doctoral scholar Julia F. Ereza mentioned within the assertion. “[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 admittedly taking place at each immediate and in each place of the universe from its earliest days to the current.”
The map is obtainable to obtain, or you may discover the brand new simulation even sooner through a YouTube introduction.
