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 ...
NASA releases images of galaxy clusters with black holes at center. This composite images shown side-by-side of two different galaxy clusters, each with a central black hole surrounded by patches ...
The Hole Idea is a 1955 Warner Bros. Looney Tunes cartoon directed and animated by Robert McKimson with character layout and background layout and paint by Richard H. Thomas. [1] The short was released on April 16, 1955.
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.
A cartoon character manipulating a portable hole. The 1955 Looney Tunes cartoon, The Hole Idea, presents a fictional account in which Calvin Q. Calculus invents the device. [2] [3]: 317 [4] [5] Another early Looney Tunes example, Beep Prepared from 1961, developed the trope further and features the Road Runner lifting a (previously ordinary) hole off the ground, carrying it, then laying it ...

Extremal black hole – black hole with the minimal possible mass that can be compatible with a given charge and angular momentum. Black hole electron – if there were a black hole with the same mass and charge as an electron, it would share many of the properties of the electron including the magnetic moment and Compton wavelength.
