China's Deep-Sea Telescope: Unveiling the Secrets of Neutrinos in the Pacific Ocean

China is constructing the Tropical Deep-sea Neutrino Telescope (Trident), the world's largest and most advanced neutrino telescope, in the South China Sea. The telescope will be anchored 3.5km below the ocean surface and will scan for cosmic neutrinos colliding with water molecules. It aims to solve the mystery of the origin of cosmic rays and explore the extreme universe. Trident will also test space-time symmetries, search for quantum gravity, and indirectly search for dark matter. The project's pilot phase is expected to be completed by 2026, with the full telescope operational by 2030.
