In black hole theory, the black hole membrane paradigm is a simplified model, useful for visualising and calculating the effects predicted by quantum mechanics for the exterior physics of black holes, without using quantum-mechanical principles or calculations.
 It models a black hole as a thin, classically radiating surface (or membrane) at or vanishingly close to the black hole's event horizon.
 This approach to the theory of black holes was created by Kip S. Thorne, R. H. Price and D. A. Macdonald.
Maximilian "Max" Goof is a fictional character who is the son of the popular Disney character Goofy.
 He first appeared in the 1992 television series "Goof Troop" as a preteen.
 He later appeared as a teenager in the spin-off movie "A Goofy Movie" (1995) and its direct-to-video sequel "An Extremely Goofy Movie" (2000).
 He appeared as a child in the direct-to-video film "Mickey's Once Upon a Christmas" (1999) and as a young adult in its sequel "Mickey's Twice Upon a Christmas" (2004).
 He also appeared in the 2001 TV series "House of Mouse" as a teenage parking valet.
V404 Cygni is a microquasar and a binary system consisting of a black hole with a mass of about and an early K companion star of mass slightly smaller than the Sun in the constellation of Cygnus.
 The star and the black hole orbit each other every at fairly close range.
 Due to their proximity and the intense gravity of the black hole, the companion star loses mass to an accretion disk around the black hole and ultimately to the black hole itself.
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 unbilled).
 The music for the film was composed by John Barry.
 It was the first film from Walt Disney Productions to receive a PG rating.
 The film was released on December 18, 1979 in the United Kingdom and on December 21, 1979 in the United States.
A Goofy Movie is a 1995 American animated musical road comedy-drama film, produced by DisneyToon Studios and Walt Disney Television Animation.
 Directed by Kevin Lima, the film is based on The Disney Afternoon television series "Goof Troop", and acts as a follow-up to the show.
The ergosphere is a region located outside a rotating black hole's outer event horizon.
 Its name was proposed by Remo Ruffini and John Archibald Wheeler during the Les Houches lectures in 1971 and is derived from the Greek word "ergon", which means "work".
 It received this name because it is theoretically possible to extract energy and mass from this region.
 The ergosphere touches the event horizon at the poles of a rotating black hole and extends to a greater radius at the equator.
 With a low spin of the central mass the shape of the ergosphere can be approximated by an oblated spheroid, while with higher spins it resembles a pumpkin-shape.
 The equatorial (maximum) radius of an ergosphere corresponds to the Schwarzschild radius of a non-rotating black hole; the polar (minimum) radius can be as little as half the Schwarzschild radius (the radius of a non-rotating black hole) in the case that the black hole is rotating maximally (at higher rotation rates the black hole could not have formed).
In astrophysics, an extreme mass ratio inspiral (EMRI) is the orbit of a relatively light object around a much heavier (by a factor 10,000 or more) object, that gradually decays due the emission of gravitational waves.
 Such systems are likely to be found in the centers of galaxies, where stellar mass compact objects, such as stellar black holes and neutron stars, may be found orbiting a supermassive black hole.
 In the case of a black hole in orbit around another black hole this is an extreme mass ratio binary black hole.
 The term EMRI is sometimes used as a shorthand to denote the emitted gravitational waveform as well as the orbit itself.
Goof Troop is an American animated comedy television series produced by Walt Disney Television Animation.
 The series focuses on the relationship between single father Goofy and his son, Max; as well as their neighbors Pete and his family.
 Created by Peter Montgomery, the main series of 65 episodes aired in first-run syndication from 1992 to 1993 on "The Disney Afternoon" programming block, while an additional thirteen episodes aired on Saturday mornings on ABC.
 A Christmas special was also produced, which aired in syndication on November 1, 1992.
 Walt Disney Pictures released two films based on the television series: the theatrical "A Goofy Movie", released on April 7, 1995; as well as the direct-to-video sequel and television series finale "An Extremely Goofy Movie", released on February 29, 2000.
The Penrose process (also called Penrose mechanism) is a process theorised by Roger Penrose wherein energy can be extracted from a rotating black hole.
 That extraction is made possible because the rotational energy of the black hole is located not inside the event horizon of the black hole, but on the outside of it in a region of the Kerr spacetime called the ergosphere, a region in which a particle is necessarily propelled in locomotive concurrence with the rotating spacetime.
 All objects in the ergosphere become dragged by a rotating spacetime.
 In the process, a lump of matter enters into the ergosphere of the black hole, and once it enters the ergosphere, it is forcibly split into two parts.
 For example, the matter might be made of two parts that separate by firing an explosive or rocket which pushes its halves apart.
 The momentum of the two pieces of matter when they separate can be arranged so that one piece escapes from the black hole (it "escapes to infinity"), whilst the other falls past the event horizon into the black hole.
 With careful arrangement, the escaping piece of matter can be made to have greater mass-energy than the original piece of matter, and the infalling piece has negative mass-energy.
 Although momentum is conserved the effect is that more energy can be extracted than was originally provided, the difference being provided by the black hole itself.
 In summary, the process results in a slight decrease in the angular momentum of the black hole, which corresponds to a transference of energy to the matter.
 The momentum lost is converted to energy extracted.
An Extremely Goofy Movie is a 2000 American direct-to-video animated coming-of-age slapstick-comedy film made by Walt Disney Pictures, produced by Walt Disney Television Animation, and directed by Douglas McCarthy.
 It is the sequel to the 1995 film "A Goofy Movie", which was based on the animated television series "Goof Troop".
 The story follows Max's freshman year at college, which is compounded by his father's presence when Goofy arrives at the same college to get a degree because of his failure to complete college.
 This film also serves as the television series finale of "Goof Troop".
