Born of science fiction, thinking about time travel has allowed us to visit possible and lost worlds, and rediscover the past through modern eyes. It also raises big puzzles: If you travelled back in time and killed your grandfather when he was a young man, would you still exist? Would changing the past mean you returned to a different present? What about travelling to the future? Two philosophers and a science fiction writer discuss time travel, and how thinking and writing about it has changed science and philosophy.
