Cosmologists create 4,000 virtual universes to solve Big Bang mystery

The reconstruction method winds back the evolution from right to left on this illustration to reproduce the primordial density fluctuations from the current galaxy distribution. Cosmologists are pressing rewind on the first instant after the Big Bang by simulating 4,000 versions of the universe on a massive supercomputer.  The goal is to paint a picture of the immediate aftermath of the Big Bang, when the observable universe suddenly expanded 1 trillion trillion times in size in the tiniest sliver of a microsecond. By applying the method used for the simulations to real observations of today s universe, researchers hope to arrive at an accurate understanding of what this inflationary period looked like. 

The ATERUI II supercomputer is taking us back to the dawn of time

While no one really knows why inflation happened so fast, simulations that evolved all those galaxies are now offering a look far back in time. By applying this analysis method, it is expected that inflation theory can be verified efficiently,” said astrophysicist Masato Shirasaki of the National Astronomical Observatory of Japan (NAOJ), who recently led a study recently published in Physical Review D. “It is, so to speak, a time-saving technique that can scientifically verify the beginning of the universe.” After the Big Bang, the universe blew up into something gargantuan right after it came onto the scene. Even astronomers have a hard time fathoming the speed at which this happened. If someone had been there with a camera about 13.8 billion years ago, our technology still might have been no match for a phenomenon in which the size of the universe expanded to over a trillion, trillion times its size in less than a trillionth of a trillionth of a microsecond. That takes a

ATERU II Supercomputer Turned Back Time for Astronomers to See Early State of Universe

17 February 2021, 10:23 am EST By The state of the universe during its early days is still a big question even for astronomers, but with the help of technology, experts are able to create simulations based on what they know and help answer the mysteries of the universe one by one, such as the case of scientists from Japan who used a supercomputer to help turn back the cosmic clock.

Using a Supercomputer to Test a Method In a report by Phys.org, astronomers used the ATERU II supercomputer at the National Astronomical Observatory of Japan (NAOJ) to create 4,000 simulations of the universe and with it, the scientists were able to test a reconstruction method.
