Explore the fascinating world of gravitational waves in this 54-minute lecture by Professor Sheila Rowan. Delve into Einstein's General Theory of Relativity and understand how these ripples in space-time are produced by some of the most energetic phenomena in our universe, including black holes, neutron stars, and supernovae. Learn about the groundbreaking detection of gravitational waves by the Laser Interferometer Gravitational-wave Observatory (LIGO) and its significance in ushering in a new era of astronomy. Discover the nature of gravitational waves, their cosmic sources, detection methods, and the exciting future prospects of this field. Gain insights into Professor Rowan's research on ultra-sensitive mechanical systems, materials with ultra-low mechanical loss, and the construction of mechanically-stable optical systems for interferometric applications.
