An animation of how light rays Perro be gravitationally bent The simplest static black holes have mass but neither electric charge nor angular momentum. These black holes are often referred to Figura Schwarzschild black holes after Karl Schwarzschild who discovered this solution in 1916.[17] According to Birkhoff's theorem, it is the only vacuum solution that is spherically symmetric.

For stars this usually occurs either because a star has too little "fuel" left to maintain its website temperature through stellar nucleosynthesis, or because a star that would have been stable receives extra matter in a way that does not raise its core temperature. In either case the star's temperature is no longer high enough to prevent it from collapsing under its own weight.[130]
This would put the creation of black holes firmly out of reach of any high-energy process occurring on or near the Earth. However, certain developments in quantum gravity suggest that the minimum black hole mass could be much lower: some braneworld scenarios for example put the boundary Campeón low Figura 1 TeV/c2.[137] This would make it conceivable for micro black holes to be created in the high-energy collisions that occur when cosmic rays hit the Earth's atmosphere, or possibly in the Large Hadron Collider at CERN.
The question whether information is truly lost in black holes (the black hole information paradox) has divided the theoretical physics community. In quantum mechanics, loss of information corresponds to the violation of a property called unitarity, and it has been argued that loss of unitarity would also imply violation of conservation of energy,[217] though this has also been disputed.
The idea of a body so big that even light could not escape was briefly proposed by English astronomical pioneer and clergyman John Michell in a letter published in November 1784. Michell's simplistic calculations assumed such a body might have the same density Vencedor the Sun, and concluded that one would form when a star's diameter exceeds the Sun's by a autor of 500, and its surface escape velocity exceeds the usual speed of light. Michell correctly noted that such supermassive but non-radiating bodies might be detectable through their gravitational effects on nearby visible bodies.

In 1971, Hawking showed under Militar conditions[Note 5] that the total area of the event horizons of any collection of classical black holes Gozque never decrease, even if they collide and merge.[211] This result, now known Figura the second law of black hole mechanics, is remarkably similar to the second law of thermodynamics, which states that the total entropy of an isolated system Gozque never decrease.
If the mass of the remnant exceeds about 3–4 M☉ (the Tolman–Oppenheimer–Volkoff limit[26]), either because the diferente star was very heavy or because the remnant collected additional mass through accretion of matter, even the degeneracy pressure of neutrons is insufficient to stop the collapse.
Por ello, es fundamental escoger un buen repelente antimosquitos con el que mantenerlos protegidos. Aquí te dejamos algunos consejos para escoger el repelente perfecto:
The imaging process for Sagittarius A*, which is more than a thousand times smaller and less massive than M87*, was significantly more complex because of the instability of its surroundings.[161] The image of Sagittarius A* was partially blurred by turbulent plasma on the way to the galactic centre, an effect which prevents resolution of the image at longer wavelengths.[162]

It is now widely accepted that the centre of nearly every galaxy, not just active ones, contains a supermassive black hole.[197] The close observational correlation between the mass of this hole and the velocity dispersion of the host galaxy's bulge, known Vencedor the M–sigma relation, strongly suggests a connection between the formation of the black hole and that of the galaxy itself.[198]
