China is preparing to dive into the ocean depths to elucidate the mysteries of “ghost particles”, neutrinos. China’s new detector, called TRIDENT, will take root 3,500 meters below the surface of the Pacific Ocean. Western.

The TRIDENT (Tropical Deep-sea Neutrino Telescope – telescope of neutrinos in deep tropical waters) will scrutinize the rare flashes of light (Light is the whole electromagnetic waves visible to the eye…) produced by these elusive particles. In activity (The term activity can designate a profession.) from 2030, it will look for these flashes when neutrinos briefly interact with the water. Every second (Second is the feminine of the adjective second, which comes immediately following the first or which…), approximately 100 billion neutrinos pass through each centimeter. .01 meter.) square (A square is a regular polygon with four sides. This means that its…) of your body. However, their electric charge (Electric charge is a fundamental property of matter which respects the principle of …) zero and their almost zero mass make their interaction (An interaction is an exchange of information, affects or energy between two agents within…) with matter (Matter is the substance which composes any body having a tangible reality. Its…) extremely weak.
TRIDENT’s mission is to discover the origins of neutrinos, even if they are several billion light years away, where stellar explosions and galactic collisions occur. According to Xu Donglian, chief scientist of the project, the detector will benefit from the absence of blind spots due to its proximity to the equator.
Neutrino detection remains a challenge. They interact little, but sometimes create muons that emit flashes of light. The Chinese detector will include more than 24,000 optical sensors spread over 1,211 wires anchored to the seabed. It will cover an area of 7.5 km³, far surpassing the IceCube detector in Antarctica (Antarctica (pronounced [ɑ̃.taʁk.tik] Listen) is the continent most…), currently the largest in the world.
The pilot project will begin in 2026 and the full detector will be operational in 2030. Researchers aim to push the limits of neutrino detection to reach a new frontier of sensitivity in research (Scientific research primarily refers to all actions companies with a view…) to astrophysical sources of neutrinos.
