This is essentially the question of whether general relativity is a deter ministic theory. Perhaps the most exciting arena where the validity of the conjecture is challenged is the interior of rotating black holes\, and th ere has been a lot of work in the past 50 years in identifying mechanisms ensuring that at least some formulation of the conjecture be true. It turn s out that when a nonzero cosmological constant Λ is added to the Einstei n equations\, these underlying mechanisms change in an unexpected way\, an d the validity of the conjecture depends on a detailed understanding of su btle aspects of black hole scattering theory\, surprisingly involving\, in the case of negative Λ\, some number theory. Does strong cosmic censorsh ip survive the challenge of non-zero Λ? This talk will try to address thi s Question!\n LOCATION:https://researchseminars.org/talk/CCTP_HEP/6/ END:VEVENT END:VCALENDAR
