The hidden pockets of the universe where the future can cause the past

Inside some very special black holes, there may be a boundary called a Cauchy horizon. Columnist Leah Crane explores the place beyond which physics breaks and anything is possible

Comment

Professor Sir John Pendry FRS, Chair in Theoretical Solid State Physics, Imperial College London, who has made seminal contributions to research in metamaterials and photonics, surface science, and disordered systems and localisation. Cloaking devices, perfect lenses and the super high-speed computer chips of the future are just some of the practical applications of Sir John's theoretical research.
