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 .

Jul 13, 2022 · Creating microscopic black holes using particle accelerators requires less energy than previously thought, researchers say. If physicists do succeed in creating black holes with such energies...

Jun 6, 2024 · In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain …

Another way of revealing extra dimensions would be through the production of “microscopic black holes”. What exactly we would detect would depend on the number of extra dimensions, the mass of the black hole, the size of the dimensions and the energy at which the black hole occurs.

Mar 29, 2010 · ‘What this incredible temperature means is that mini black holes of tiny mass ‘evaporate’ into the far, far colder space around them almost infinitely fast. Their expected lifetime is around one octillionth of a nanosecond – so that they pop out of existence again almost as soon as they are created.’

Nov 1, 2019 · An entirely new class of black holes may be lurking in the universe, and these may be far tinier than what scientists have found before, according to new findings.

Micro black holes are very small black holes. Because they are small, they may shrink and disappear due to Hawking radiation. [1] They may exist in nature as primordial black holes.

Dec 2, 2024 · Scientists have proposed an intriguing new way to search for primordial black holes – microscopic objects formed in the early universe that could explain dark matter. These cosmic remnants might leave behind distinctive signatures ranging from hollow asteroids in space to microscopic tunnels in everyday materials like rocks and glass.

Nov 12, 2004 · In addition to these astrophysical and cosmological aspects, there is another route of investigation that is particularly promising for microscopic black holes, namely at particle accelerators.

The CMS experiment at CERN's Large Hadron Collider (LHC) has completed a search for microscopic black holes produced in high-energy proton-proton collisions. No evidence for their production was found and their production has been excluded up to a black hole mass of 3.5-4.5 TeV (10 12 electron volts) in a variety of theoretical models.
