Are we living in a simulation? Elon Musk thinks we definitely could be, and it seems he is not alone. The idea that we might simply be products of an advanced post-human civilisation, that are simply running a simulation of our universe and everything it contains, has taken hold over the last few years. Brian Cox and Robin Ince are joined on stage by comedian Phill Jupitus, Philosopher Professor Nick Bostrom and Neuroscientist Professor Anil Seth to ask what the chances are that are living in some Matrix like, simulated world and more importantly, how would we ever know? Producer: Alexandra Feachem.
