Prof. Nergis Mavalvala, dean of the MIT School of Science, joins Bob McDonald of CBC’s “Quirks & Quarks” to discuss how 10 years after LIGO’s first detection of gravitational waves the observatories are still “helping scientists better understand the life cycles of stars, the nature of gravity, and transforming the way we explore the farthest reaches of space.” Mavalvala shares: "Scientists have been able to design and construct these instruments that are capable of measuring imperceptibly small changes in spacetime distance, and in the past 10 years the sensitivity of these instruments has improved. That’s what is allowing us to make greater discoveries.”
