MIT researchers Lisa Barsotti, Deep Chatterjee, and Victoria Xu explore how developments in gravitational wave detection are enabling a better understanding of the universe. Barsotti notes that in the future gravitational wave science should enable us to “learn more about dark matter, about primordial black holes to try to solve some of the biggest mysteries in our universe.” Xu notes that “the detection of gravitational waves is a completely new window that has opened into our universe.”
