China is building the world's largest underwater telescope : Know why?

The largest "ghost particle" detector in the world is being constructed by Chinese scientists 11,500 feet (3,500 metres) below the ocean's surface.

The Tropical Deep-sea Neutrino Telescope (TRIDENT), also known as the "Ocean Bell" or Hai ling in Chinese, is a telescope that will be permanently moored to the Western Pacific Ocean's bottom.

When it's finished in 2030, it will search the ocean floor for infrequent bursts of light produced by elusive particles as they momentarily become visible.

Your body contains roughly 100 billion neutrinos, or ghost particles, per square centimetre per second.

Nevertheless, in keeping with its eerie moniker, neutrinos hardly interact with other forms of matter due to their nearly negligible mass and nonexistent electrical charge.

However, by slowing down neutrinos, physicists are able to determine that some of the particles originated in ancient, cataclysmic star explosions and galactic collisions that occurred billions of light-years ago.

In the cosmos, neutrinos are the most abundant subatomic particle, surpassed only by photons.

They are created by radioactive decay, cosmic rays, massive supernova explosions, nuclear reactors on Earth, particle accelerators, and radioactive fire in stars.

As neutrinos travel through water or ice, they sometimes create particle byproducts called muons that give off flashes of light.

By studying the patterns these flashes make, scientists can reconstruct the energy, and sometimes the sources, of the neutrinos.

But to increase the chances of ghost particle interactions, detectors have to sit under a lot of water or ice.
