What Is Vacuum Decay?

Brian Cox and Robin Ince are back for new series, for now at least, as they take an upbeat look at all the different ways our Universe might end. They are joined by legendary comedians Steve Martin and Eric Idle, alongside astrophysicist Katie Mack and cosmologist Brian Greene, to find out which end the panel might prefer. Will we go with the Big Rip or possibly the Big Crunch, or even death by giant bubble that expands so rapidly it wipes out our universe almost instantly? On that cheery note the panel vote for their favourite apocalyptic ending and wonder what they might be doing and what they hope to have achieved when the final moment comes.
