CHINA'S NEW DARK MATTER LAB IS BIGGEST AND DEEPEST YET

Summary from the TLDR newsletter

The world's deepest and largest underground laboratory is around 2,400 meters below the Jinping Mountains in southwest China. The enormous space, with a sprawling capacity of 330,000 cubic meters, is home to scientists studying dark matter, a hypothetical substance thought to make up more than 80% of the mass in the Universe. It opened in 2010 but only became operational in December 2023. The layers of rock above the laboratory shield it from background noise such as cosmic rays.
