The Nottingham experiment was based on the theory that an area immediately outside the event horizon of a rotating black hole — a black hole's gravitational point of no return — will be dragged round by the rotation and any wave that enters this region, but does not stray past the event horizon, should be deflected and come out with more energy than it carried on the way in — an effect known as superradiance.
