Smallest black hole possible
Webb2 apr. 2008 · The Smallest Known Black Hole. NASA scientists have identified the lightest black hole yet, just 3.8 times the mass of the sun, in a binary star system in the Milky Way known as XTE J1650-500. 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 that such black holes were created in the high-density environment of the early Uni…
