Simulation of early evolving universe

Scientists have developed a most close simulation of the early evolving universe with the help of NASA’s powerful supercomputer i.e. Pleiades supercomputer located at NASA’s Ames Research Center in Silicon Valley of California.

Scientists have used the Bolshoi simulation on Pleiades to show the evolution of large scale structures in the Universe. The word Bolshoi is taken from Russian word meaning “grand” or “big”. Bolshoi simulation is a cosmological simulation available to astrophysicists around the world and is most accurate in evolving the large scale structures of the Universe.

Pleiades is the seventh most powerful computer in the world and it took 18 days and 6 million CPU hours taken by 160,000 processors working in combination for the computer to work on Bolshoi code.

William Thigpen, systems and engineering branch chief in the NASA Advanced Supercomputing (NAS) Division at NASA’s Ames Research Center, said,

“The Bolshoi simulation is an excellent example of work done in support of NASA’s science goal to understand how stars, galaxies and planets are formed, in order to get a picture of how the universe has changed over billions of years,”

Still the simulation is showing results according to what scientists have seen in the actual universe.
