    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.

    Gaia BH3 is the first black hole discovered from preliminary Gaia DR4 astrometric data. [2] The black hole and star orbit the system barycentre every 11.6 years, with an orbital distance ranging from 4.5–29 AU. [3] The black hole's mass is 32.70 M ☉, the heaviest known stellar black hole in the Milky Way.

    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.
