Grab it Explore the complex world of non-linear behavior in perturbed black holes through this 58-minute conference talk by Luis Lehner at BIMSA. Delve into the theoretical arguments that reveal rich phenomena potentially observable through gravitational wave mergers. Gain insights into the challenges faced at both fundamental and practical levels in understanding non-linear behavior, contrasting it with the relatively simple description of linear behavior in perturbed black holes. Discover the important implications these findings have for the search for new physics in gravitational wave astronomy.
