Explore the future of gravitational wave detection in this 44-minute lecture by Bangalore Sathyaprakash from Penn State. Delve into the impact of Advanced LIGO/Virgo's gravitational wave detections on physics, from field theory to stellar evolution and cosmology. Learn about the upcoming more sensitive ground-based detectors and space-based observatories, and understand the need for precision modeling of gravitational-wave signals. Discover how this research is fostering new connections between theoretical communities, particularly field theorists and classical relativists. Gain insights into the challenges that theory must overcome for next-generation gravitational-wave experiments and the promising emerging tools from classical and quantum field theory.
