https://www.youtube.com/watch?v=TQhNS3u6f5Q


Is time travel possible? Science fiction has monopolised this question for so long, we thought it was time to investigate what real science has to say. In this lecture which will cover fascinating ideas in physics that lead from Einstein's theories of relativity, Jim Al-Khalili will treat us to a look at dimensions, investigate how we can possibly imagine living in curved space-time, and how this curvature can cause a black hole to be punched in space. Borrowing from science fiction, Professor Al-Khalili will also explore the more problematic question of time travel into the past and the paradoxes that arise. And finally, investigate how we could go about constructing a time machine!
