Ask A Genius 1284: The Conservation of Information in Quantum Mechanics and Cosmology

 Rick Rosner: In physics, there are many conservation laws or principles that are generally supported by experimental evidence. For example, energy is conserved, and momentum is conserved. The conservation of information is a more complex and debated topic, particularly in quantum mechanics and cosmology. While there are arguments that information is conserved in quantum mechanical …
