Brian Cox and Robin Ince look at the weird and wacky world of black holes as they ask a question that has been troubling scientists for years: What happens if you push Matt Lucas into a black hole? They are joined by the very game Matt Lucas, alongside Cosmologist Sean Carroll and Astrophysicist Janna Levin to discover just how strange things might get for our intrepid volunteer, as he ventures into the interior of a black hole. From Holograms to spagettification, it turns out science fact is far more bizarre than anything that science fiction could possibly imagine. Producer: Alexandra Feachem
