Brian Cox and Robin Ince are subject to a non-hostile takeover by comedian and non-physicist Jo Brand, as she challenges the panel to help her understand the almost unbelievable world of cheeky particles who may or may not be in several places at once. To help Jo get to grips with the bizarre and strange world of our quantum universe, Brian and Robin are joined by theoretical physicist Prof Ben Allanach from the University of Cambridge and cosmologist Prof Fay Dowker from Imperial College London, who introduce Jo to the weird and wonderful ways of quantum theory, dead and alive cats and multiverses.
