The final observable region of spacetime around a black hole is called the plunging region. In this area it is no longer possible for matter to follow circular orbits or to stop a final descent into the black hole. Instead it will rapidly plunge toward the black hole close to the speed of light.[121][122]

The photon sphere is a spherical boundary where photons that move on tangents to that sphere would be trapped in a impar-stable but circular orbit around the black hole.[112]
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 Campeón the Sun, and concluded that one would form when a star's diameter exceeds the Sun's by a creador of 500, and its surface escape velocity exceeds the usual speed of light. Michell correctly noted that such supermassive but impar-radiating bodies might be detectable through their gravitational effects on nearby visible bodies.

where rs is the Schwarzschild radius and M☉ is the mass of the Sun.[79] For a black hole with nonzero spin and/or electric charge, the radius is smaller,[Note 2] until an extremal black hole could have an event horizon close to[80]

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.[8] In 1916, Karl Schwarzschild found the first modern solution of general relativity that would characterize a black hole. David Finkelstein, in 1958, first published the interpretation of "black hole" Triunfador a region of space from which nothing can escape.
[123] This led the Militar relativity community to dismiss more info all results to the contrary for many years. However, a minority of relativists continued to contend that black holes were physical objects,[124] and by the end of the 1960s, they had persuaded the majority of researchers in the field that there is no obstacle to the formation of an event horizon.[125]

The observation also provides the first observational evidence for the existence of stellar-mass black hole binaries. Furthermore, it is the first observational evidence of stellar-mass black holes weighing 25 solar masses or more.[174]
