Micro black holes, also called mini black holes or quantum mechanical black holes, are hypothetical tiny (<1 M☉) black holes, for which quantum mechanical effects play an important role. The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking. It is possible … See more In an early speculation, Stephen Hawking conjectured that a black hole would not form with a mass below about 10 kg (roughly the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently … See more Formation in the early Universe Production of a black hole requires concentration of mass or energy within the corresponding See more It is possible, in some theories of quantum gravity, to calculate the quantum corrections to ordinary, classical black holes. Contrarily to conventional black holes, which are solutions of gravitational field equations of the general theory of relativity, … See more Hawking radiation In 1975, Stephen Hawking argued that, due to quantum effects, black holes "evaporate" by a process now referred to as Hawking radiation in … See more Feasibility of production In familiar three-dimensional gravity, the minimum energy of a microscopic black hole is 10 TeV (equivalent to 1.6 GJ or 444 kWh), … See more • Star portal • Stars portal • Black hole electron • Black hole starship See more • Page, Don N.
