Understanding Our Universe From 2 KM Underground

By going deep underground and creating ultra-clean conditions, it is possible to produce the lowest radioactivity laboratory in the world. There we can address very fundamental questions about our Universe: How does the Sun burn? What are the abundant dark matter particles in the spaces between the stars? What are the properties of neutrinos, elusive particles that are one of the fundamental building blocks of nature? How do these particles influence how our Universe evolves? This talk describes experiments that take place at underground labs internationally and address these questions.
