Adam Roberts/ Bryan Roberts/ Emily Thomas
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.
