The Enigma of Black Hole Horizons

Explore the fascinating mysteries of black hole horizons in this physics lecture presented by Abhay Ashtekar at the Raman Research Institute. Delve into fundamental questions about the nature of black holes, examining what actually forms during gravitational collapse and undergoes quantum radiation evaporation. Learn about the counterintuitive properties of event horizons, including their peculiar ability to form in anticipation of future events, and discover alternative theoretical frameworks for understanding black hole phenomena. Gain insights into both classical general relativity applications in black hole mergers and quantum processes in black hole evaporation, presented in an accessible manner suitable for physics and astronomy students and enthusiasts. Through this comprehensive exploration of gravitational wave observations and theoretical physics, develop a deeper understanding of these ubiquitous cosmic phenomena that continue to challenge our understanding of the universe.
