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.
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 ...

SMSS J215728.21-360215.1, commonly known as J2157-3602, is one of the fastest growing black holes and one of the most powerful quasars known to exist as of 2021.The quasar is located at redshift 4.75, [1] corresponding to a comoving distance of 2.5 × 10 10 ly from Earth and to a light-travel distance of 1.25 × 10 10 ly.
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 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.
IRAS 13224-3809 is a highly active and fluctuating Seyfert 1 galaxy in the constellation Centaurus [2] about 1 billion light-years from Earth. [3] [5] [6] The galaxy is notable due to its centrally-located supermassive black hole that is closely studied by astronomers using x-ray astronomy, particularly X-ray reverberation echo mapping techniques, in an effort to better understand the inner ...
