Can Information Escape a Black Hole? The Puzzle That Changed Physics

Explore one of modern physics' most profound puzzles in this public lecture that examines the black hole information paradox and its revolutionary impact on our understanding of the universe. Delve into the fundamental conflict between general relativity and quantum mechanics when applied to black holes, starting with Stephen Hawking's original formulation of the paradox that questioned whether information falling into a black hole disappears forever. Discover how this seemingly simple question challenges the very foundations of quantum mechanics and learn why the apparent impossibility of information escaping black holes creates such a significant theoretical crisis. Understand the crucial role of quantum entanglement in resolving this paradox and examine recent breakthrough discoveries showing that information does indeed escape black holes, albeit in an extremely scrambled form. Follow the journey from the initial formulation of the problem through to cutting-edge research in quantum gravity and the AdS/CFT correspondence that has transformed our understanding of black hole physics. Gain insight into how this paradox has driven advances in theoretical physics and brought us closer to unifying gravity with quantum theory, while appreciating the broader implications for our understanding of information, entropy, and the fundamental nature of spacetime itself.
