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 .
Date: 30 June 1908; 116 years ago (): Time: 07:17: Location: Podkamennaya Tunguska River, Yeniseysk Governorate, Russian Empire: Coordinates: 1]: Cause: Probable meteor air burst of small asteroid or comet: Outcome: Flattened 2,150 km 2 (830 sq mi) of forest Devastation to local plants and animals: Deaths: Up to 3 possible [2]: Property damage: A few damaged buildings: The Tunguska event was a ...
Black hole evaporation takes a long time relative to the current age of the universe, for black holes larger than a proton. When particles escape, the black hole loses a small amount of its energy and therefore some of its mass (mass and energy are related by Einstein's equation E = mc 2). Consequently, an evaporating black hole will have a ...

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be? Mysterious flashing seen near supermassive black hole.
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 ...
Three stellar black holes found in our galaxy, Gaia BH1, Cygnus X-1 and Gaia BH3, have masses that are 10, 21 and 33 times that of the sun, respectively.
A simulated particle collision in the LHC. The safety of high energy particle collisions was a topic of widespread discussion and topical interest during the time when the Relativistic Heavy Ion Collider (RHIC) and later the Large Hadron Collider (LHC)—currently the world's largest and most powerful particle accelerator—were being constructed and commissioned.
