Brian Cox and Robin Ince are joined by Monty Python's Eric Idle, and cosmologists Dr Netta Engelhardt and Dr Janna Levin as they tackle one of the biggest challenges in cosmology. What happens when you throw something (Robin!) into a black hole? Is the information about Robin lost forever, or is there a chance, sometime in the far future, a super intelligent alien civilisation could piece back some key information to discover proof he ever existed? Are Robin and his cardigans lost for all eternity? Executive Producer: Alexandra Feachem
