A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
For black holes, this manifests as Hawking radiation, and the larger question of how the black hole possesses a temperature is part of the topic of black hole thermodynamics. For accelerating particles, this manifests as the Unruh effect , which causes space around the particle to appear to be filled with matter and radiation.
In Interstellar, a key plot point involves a planet, which is close to a rotating black hole and on the surface of which one hour is equivalent to seven years on Earth due to time dilation. [44] Physicist Kip Thorne collaborated in making the film and explained its scientific concepts in the book The Science of Interstellar. [45] [46]

Black holes have previously been spotted orbiting with one other star or one other black ho. ... This system is located about 7,800 light-years from Earth in the constellation Cygnus. A light-year ...
Stellar black hole – black hole formed by the gravitational collapse of a massive star. [1] They have masses ranging from about three to several tens of solar masses. Intermediate-mass black hole – black hole whose mass is significantly more than stellar black holes yet far less than supermassive black holes.
The galaxy SDSS1335+0728, located 300 million light-years away in the constellation Virgo, seems to be experiencing an extraordinary event in real time.
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.
