Researchers have created the first laboratory analogue of the 'black hole bomb'.
It consists of a rotating aluminium cylinder, placed inside the layers of coils that generate magnetic fields that rotate around it, at controllable speeds.
In 1972, physicists William Press and Saul Teukolsky has described a theoretical phenomenon called a black hole bomb.
In 1969, the British mathematical physicist and Nobel laureate Sir Roger Penrose proposed a way to extract energy from a rotating black hole.
