  2. Black hole starship - Wikipedia

    en.wikipedia.org/wiki/Black_hole_starship

    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.

    A replacement engine was installed [82] and a third static fire was attempted on March 26. [83] A 10 km flight test was conducted in heavy fog on March 30. The test included engine cutoffs, flip maneuver, flap control and descent, along with a visible fire on engine 2 [84] during the ascent. Just after the defective engine was re-ignited for ...

    Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.

    This is a list of known black holes that are close to the Solar System. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [1] Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more

    en.wikipedia.org/wiki/Blandford–Znajek_process

    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.

  9. Binary black hole - Wikipedia

    en.wikipedia.org/wiki/Binary_black_hole

    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 ...
