119. The Science of Time Travel – Part One (2012)

A short video by science journalist Dan Falk, author of In Search of Time (St. Martin’s Press 2008).

Of all the plot devices used by science fiction writers, nothing captures the imagination as much as time travel. But what does science have to say about it? It turns out that travelling into the future is pretty straightforward – it’s built into Einstein’s theory of relativity. (9 minutes.)
