Is time travel possible?

Ever wanted to meet your historical heroes or explore the inventions of the future? Travelling in time has long been a dream of writers and filmmakers, but what does science tell us about how possible this would be to achieve in real life?

We explore how physics shows us that time runs at different rates depending on where we are and how we’re moving - time goes more slowly for astronauts on the international space station for example. We hear about the very dangerous ways we could possibly exploit this to skip forwards through time and into Earth’s future, and we do the maths on wormholes, to see if they offer a possible portal to our past.
