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. [1] The concept that black holes may exist that are smaller than stellar mass was introduced in 1971 by Stephen Hawking .
Depending on the model, primordial black holes could have initial masses ranging from 10 −8 kg [17] (the so-called Planck relics) to more than thousands of solar masses. . However, primordial black holes originally having masses lower than 10 11 kg would not have survived to the present due to Hawking radiation, which causes complete evaporation in a time much shorter than the age of the ...
A black hole of one solar mass (M ☉ = 2.0 × 10 30 kg) takes more than 10 67 years to evaporate—much longer than the current age of the universe at 1.4 × 10 10 years. [22] But for a black hole of 10 11 kg, the evaporation time is 2.6 × 10 9 years. This is why some astronomers are searching for signs of exploding primordial black holes.
Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the universe. But can it be proven?
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.
A black hole is a massive, ... entropy is understood as counting the number of microscopic configurations of a system that have the same macroscopic qualities, such ...
Scientists argue that primordial black holes should have caused the Higgs field to collapse, preventing the universe's formation, challenging current models.
Hypothetical black hole may refer to: Micro black hole, a microscopic black hole proposed to have formed in the early universe; Intermediate mass black hole, a black hole of a mass between a stellar mass black hole and a supermassive black hole; Direct collapse black hole: a black hole formed from the collapse of hydrogen, rather than from a star
