The mind-bending art of deep time

Short-sightedness may be the greatest threat to humanity, says conceptual artist Katie Paterson, whose work engages with deep time -- an idea that describes the history of the Earth over a time span of millions of years. In this lively talk, she takes us through her art -- a telephone line connected to a melting glacier, maps of dying stars – and presents her latest project: the Future Library, a forested room holding unread manuscripts from famous authors, not to be published or read until the year 2114.
