00:00Deep beneath a hill of South China's Guangdong province lies a scientific marvel,
00:04one that could unlock the mysteries of the universe.
00:07China has installed the centerpiece of the world's largest transparent spherical neutrino detector,
00:12buried 700 meters underground, to capture the elusive ghost particles known as neutrinos.
00:18This 12-story-tall acrylic sphere, with a diameter of 35.4 meters,
00:23is housed inside a 44-meter-deep cylindrical water tank and secured by a robust steel frame.
00:30Surrounding the sphere are 45,000 photomultiplier tubes,
00:35advanced sensors designed to detect faint flashes of light produced when neutrinos interact with the detector's medium.
00:41Once operational in 2025, this detector will offer insights into the infinitesimally small and the infinitely vast,
00:49advancing our understanding of the universe over the next 30 years.
