This animation shows two massive black holes in the OJ 287 galaxy. The smaller black hole orbits the larger one, which remains stationary in the animation and is surrounded by a disk of gas. When the smaller black hole crashes through the disk, it produces a flare brighter than 1 trillion stars. But the smaller black hole's orbit is elongated ...
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 ...
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. [1] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
It was an extraordinarily accurate prediction. All of the dozen candidate stellar black holes in our galaxy (the Milky Way) are in X-ray compact binary systems. [19] Michell's ideas about gravity and light interested William Herschel, who tried to test them with his powerful telescopes. [17]

The Black Hole is a 1979 American science fiction film directed by Gary Nelson and produced by Walt Disney Productions.The film stars Maximilian Schell, Robert Forster, Joseph Bottoms, Yvette Mimieux, Anthony Perkins and Ernest Borgnine, while the voices of the main robot characters are provided by Roddy McDowall and Slim Pickens (both uncredited).
In order to reproduce all the known outbursts, the rotation of the primary black hole is calculated to be 38% of the maximum allowed rotation for a Kerr black hole. [10] [4] The companion's orbit is decaying via the emission of gravitational radiation and it is expected to merge with the central black hole within approximately 10,000 years. [11 ...
