Getting the black hole to act as a power source and engine also requires a way to convert the Hawking radiation into energy and thrust. One potential method involves placing the hole at the focal point of a parabolic reflector attached to the ship, creating forward thrust, if such a reflector can be built.
The Blandford–Znajek process is a mechanism for the extraction of energy from a rotating black hole, [1] [2] introduced by Roger Blandford and Roman Znajek in 1977. [3] This mechanism is the most preferred description of how astrophysical jets are formed around spinning supermassive black holes.
A quasi-star (also called black hole star) is a hypothetical type of extremely large and luminous star that may have existed early in the history of the Universe. They are thought to have existed for around 7–10 million years due to their immense mass .
The Penrose process (also called Penrose mechanism) is theorised by Sir Roger Penrose as a means whereby energy can be extracted from a rotating black hole. [1] [2] [3] The process takes advantage of the ergosphere – a region of spacetime around the black hole dragged by its rotation faster than the speed of light, meaning that from the point of view of an outside observer any matter inside ...
A binary black hole (BBH), or black hole binary, is a system consisting of two black holes in close orbit around each other. Like black holes themselves, binary black holes are often divided into binary stellar black holes , formed either as remnants of high-mass binary star systems or by dynamic processes and mutual capture; and binary ...
In other words, if enough radiation is aimed into a region of space, the concentration of energy can warp spacetime so much that it creates a black hole. This would be a black hole the original mass–energy of which was in the form of radiant energy rather than matter; [ 1 ] however, there is currently no uniformly accepted method of ...

The location of the ISCO, the ISCO-radius (), depends on the mass and angular momentum (spin) of the central object. The ISCO plays an important role in black hole accretion disks since it marks the inner edge of the disk.
