Physicists are searching for answers to some profound questions. What is the nature of dark matter and dark energy? What is the origin of mass? What happened to primordial antimatter? In this lecture, Anil Ananthaswamy talks about some of the telescopes and experiments at the cutting-edge of cosmology today, operating in some of the most extreme environments on Earth, including Lake Baikal in Siberia, an underground mine in northern Minnesota, the Atacama Desert in the Chilean Andes and even Antarctica.
