Black hole starship
In astronautics, a black hole starship is the suggestion that an artificial black hole could be used for spacecraft propulsion in a starship capable of interstellar travel. The concept was first discussed in science fiction, notably in the book Imperial Earth by Arthur C. Clarke, and in the work of Charles Sheffield, in which energy extracted from a Kerr–Newman black hole is described as powering the rocket engines in the story "Killing Vector" (1978).
