About this episode

Renato Renner discusses the logical contradictions within quantum mechanics and their implications for the theory's foundations.

Renato Renner (ETH Zurich) proves quantum mechanics contains logical contradictions that undermine its foundations.Quantum theory may be the most successful theory in history — and Renato Renner has proved it can't consistently describe itself. This is not a philosophical objection. It's a theorem. From there it spirals into black holes, reference frames, and why some of his students refused to continue working on the subject. This one is a quiet storm, blending the foundations of physics with something uncomfortably personal: the question of what you are.
