Neutrino experiment may help explain origin of universe

Scientists may be one step closer to solving some of the biggest mysteries of the universe as a neutrino experiment in southern China returned promising results.

A team from China's National Supercomputer Center in Guangzhou using the world's fastest supercomputer Tianhe-2 have completed a simulation involving three trillion neutrinos and dark matter particles.

Zhang Tongjie of Beijing Normal University and lead researcher of the project, has described a "video" simulating the elongated evolution of the universe, produced thanks to Tianhe-2, which worked like a "high-speed camera with extremely high definition".

The supercomputer had "opened a new door" to the study of neutrinos, which could greatly expedite understanding of the origin and evolution of the universe, Zhang said.

Neutrinos are sometimes known as "ghost particles" because they interact so weakly with other forms of matter. They are among the most abundant - and least understood - fundamental particles. To figure out how they work, their mass must be established, but this has never been done accurately.

"At this moment, Tianhe-2 is the only supercomputer capable of conducting such an experiment," he said.

Tianhe-2, which literally means "Milky Way-2", took the top spot on a2013 list of supercomputers. It is able to operate at 33.86 petaflops per second, 33,860 quadrillion calculations.

Tianhe-2 could hold the world's fastest supercomputer title till 2018, when the U.S. is expected unveil two supercomputers three to five times faster than the Chinese system, at a cost of 325 million U.S. dollars. Endi
