Astronomers have created the magnanimous and most naturalistic simulated edition of the universe yet . The simulation allow a new flavor at the past and present of the cosmos on a plate and in item unsufferable until now , and if you sense like it , they have made it freelyavailable for anyone to download .
As reported in theMonthly Notices of the Royal Astronomical Society , the simulation is telephone Uchuu ( mean " out space " in Japanese ) . The virtual universe is contained in a cube with each side an unprecedented 9.63 billion light - class and made of 2.1 trillion particles . That ’s not enough to model planets and individual star but it reserve the external team of researchers to simulate galaxy interactions at an incredible degree of detail .
Realistic simulations like this allow us to test our theories of the universe . As it stands , evidence suggests that the cosmos is dominated by two secret components . The matter that made us and champion is only 5 percentage of the total message . Twenty - five percentage isdark matter , an inconspicuous content that surrounds extragalactic nebula , and the rest isdark Energy Department , which is believed to be responsible for the accelerated expansion of the existence .
Uchuu allows astronomers to see how the proportions of these different components affect the structures in the universe . The simulation covers the assemblage of galaxies and galaxy clump over the 13.8 billion years since the Big Bang .
“ Uchuu is like a time machine : we can go forrader , backward and blockade in metre , we can '' zoom in '' on a single galaxy or '' zoom out '' to visualise a whole cluster , we can see what is really take place at every twinkling and in every place of the existence from its earliest daylight to the nowadays , being an essential tool to study the cosmos , ” Julia F. Ereza , a graduate research worker at the Instituto de Astrofísica de Andalucía , suppose in astatement .
Uchuu was make using the supercomputer ATERUI II , which is view the earth ’s best among those devote to uranology .
" To produce Uchuu we have used … all 40,200 mainframe ( mainframe cores ) available entirely for 48 hours each month . Twenty million supercomputer hours were consumed , and 3 Petabytes of data were generated , the equivalent of 894,784,853 pictures from a 12 - megapixel cell phone , " said Pb author Tomoaki Ishiyama , an associate professor at Chiba University . Ishiyama develop the codification used to render Uchuu .
The instauration of such a simulated population will avail with the exciting , and very large , data Seth expect to be give up by thenext generation of observatoriesover the coming tenner .
