Hawking's puzzle:The black hole information paradox
Date & time Friday, 31st January, 2014 at 16:00 hrs
Some 40 years ago, Stephen Hawking showed that there was a fundamental conflict between the two main pillars of modern physics: general relativity and quantum mechanics. General relativity allows the formation of a black hole, but the subsequent evolution of the hole appears to violate the basic principles of quantum mechanics. In recent years string theory has provided a resolution to this puzzle. It turns out that quantum gravity effects modify the entire structure of the hole, turning it into a quantum 'fuzzball'. In this talk we will explain Hawking's puzzle, outline some arguments and counter arguments that were made, and present a summary of the fuzzball resolution.
