Summary:
- Researchers at the Sanford Underground Research Facility in South Dakota have reached a critical milestone in their search for dark matter, a mysterious substance that makes up about 85% of the universe's matter.
- The experiment, called LUX-ZEPLIN (LZ), is designed to detect the extremely rare interactions of dark matter particles with normal matter. To do this, the detector is located deep underground to shield it from other types of radiation.
- The successful installation of the LZ detector is an important step towards understanding the nature of dark matter, which has so far eluded direct detection despite its overwhelming presence in the universe.
