Stephen Hawking made a number of memorable contributions to physics, but perhaps his greatest was a puzzle: is information that falls into a black hole destroyed, in contradiction with the laws of quantum mechanics? The question sits squarely at the overlap of the quantum world and gravitation, a frontier of physics where direct experimental input is hard to come by. Recent progress has been revealing how subtle effects relate the radiation leaving a black hole to what happens inside. In this lecture, we will dive into the black hole information puzzle: what it is, what we have learned about it, and where it all might lead.
