Beijing: A laboratory in China has been set up 2,400 meters below the Earth’s surface to study the invisible dark matter of the universe.

The Deep Underground and Ultra-Low Radiation Background Facility for Frontier Physics Experiments (DURF) is the world’s deepest underground laboratory.

In December 2020, Tsinghua University and Yalong River Hydropower Development Company Limited began work on the DURF project near the Jinping Mountain Range in Sichuan. The project was designed for research in related frontier fields such as particle physics, nuclear astrophysics and life sciences.

The DURF laboratory reportedly provides the cleanest location on Earth to study dark matter because it is located at the deepest point.

A depth of 2,400 meters underground helps block most cosmic rays. These cosmic rays usually interfere with the observation of dark matter.
