Where is the first direct evidence of dark matter being tested in underground labs?
Quick Answer
Direct dark-matter searches are carried out in deep underground laboratories such as Gran Sasso in Italy. The depth helps shield detectors from cosmic-ray background.
The Full Story
One of the world’s major dark-matter search sites is the Gran Sasso National Laboratory in Italy. It is located under the Gran Sasso mountain, providing about 1,400 metres of rock overburden that reduces cosmic-ray interference. Experiments there, such as XENON and DARKSIDE, look for extremely rare interactions that could reveal dark matter particles. Although dark matter has not yet been directly detected, Gran Sasso remains one of the leading places in the search.
