**Black hole**— For other uses, see Black hole (disambiguation). Simulated view of a black hole (center) in front of the Large Magellanic Cloud. Note the gravitat … Wikipedia**Black hole electron**— In physics, there is a speculative notion that 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. Problems As a… … Wikipedia**Charged black hole**— A charged black hole is a black hole that possesses electric charge. Since the electromagnetic repulsion in compressing an electrically charged mass is dramatically greater than the gravitational attraction (by about 40 orders of magnitude), it… … Wikipedia**Rotating black hole**— A rotating black hole is a black hole that possesses angular momentum.Types of black holesThere are four known, exact, black hole solutions to Einstein s equations. These equations describe gravity in General Relativity. Two of these (Kerr black… … Wikipedia**Black hole thermodynamics**— In physics, black hole thermodynamics is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons. Much as the study of the statistical mechanics of black body radiation led to the… … Wikipedia**Stellar black hole**— A stellar black hole is a black hole formed by the gravitational collapse of a massive star (20 or more solar masses, though the exact amount of mass needed has not been determined and may depend on many parameters) at the end of its lifetime.… … Wikipedia**Nonsingular black hole models**— A nonsingular black hole model is a mathematical theory of black holes that avoids certain theoretical problems with the standard black hole model, including information loss and the unobservable nature of the black hole event horizon. Contents 1 … Wikipedia**BTZ black hole**— The BTZ black hole, named after Maximo Banados, Claudio Teitelboim, and Jorge Zanelli, is a black hole solution for (2+1) dimensional gravity with a negative cosmological constant.When the cosmological constant is zero, a vacuum solution of (2+1) … Wikipedia**Near-extremal black hole**— In theoretical physics, a near extremal black hole is a black hole which is not far from the minimal possible mass that can be compatible with the given charges and angular momentum. The calculations of the properties of near extremal black holes … Wikipedia**Extremal black hole**— In theoretical physics, an extremal black hole is a black hole with the minimal possible mass that can be compatible with the given charges and angular momentum.In supersymmetric theories, extremal black holes are often supersymmetric; i.e., they … Wikipedia**Fermi hole**— The idea of a Fermi hole requires some background in the idea of anti symmetrized wavefunctions. The Pauli exclusion principle is the rule that no more than two electrons can be in the same orbital. The rule traces to a deep algebraic property of … Wikipedia
