Katie Mack: The end of everything

Science has shown us the universe began with a Big Bang but what about its endgame? Will everything burn out and freeze over, or collapse in on itself, or rip into shreds? How far away are we from this happening? Embark on a cosmic journey to the end of the universe with astrophysicist, science communicator, and author of The End of Everything (Astrophysically Speaking), Katie Mack. In a public talk, Katie takes us through the latest scientific tolls and data, from space telescopes to particle colliders, to explain the big ideas and key theories of the death of the universe. Professor Tara Murphy, Head of the School of Physics, hosts this event. This podcast is a recording of a live public event held on 10 July 2025.
