Why Quantum Information is Never Destroyed

The video explores the concepts of determinism and time reversal in physics, focusing on how these principles relate to the conservation of information. It discusses the role of conservation laws and Noether's theorem, and delves into quantum mechanics, particularly the Schrödinger equation and unitarity. The video also examines different interpretations of quantum mechanics and the implications for information conservation, including the challenges posed by black holes and Hawking radiation.
