Black Holes are enigmatic objects that pepper the Universe around us. Their existence was predicted theoretically by the modern theory of gravity and has been confirmed by a wide variety of observations. Quantum Mechanics is one of the most successful theories known to humanity. Although it was originally developed to study atoms, it is believed that quantum mechanics underpins the dynamics of all physical systems. However, paradoxes arise when one attempts to apply quantum mechanics to black holes. The most famous of these - called the "information paradox" - has to do with the nature of time. This talk will describe these ideas and paradoxes, and the recent progress that has been made towards their resolution.
