Located more than 2,000 feet below the ground, China is close to completing its state-of-the-art neutrino detector.

Scientists in China have almost finished building a massive underground detector to sniff out mysterious particles called neutrinos

Underneath a granite hill in southern China, a massive detector is nearly complete that will sniff out the mysterious ghost particles lurking around us. The Jiangmen Underground Neutrino Observatory will soon begin the difficult task of spotting neutrinos: tiny cosmic particles with a mind-bogglingly small mass.

Scientists believe neutrinos, or "ghost particles" as they've been called, could have helped write the earliest rules of matter. View on euronews
