By the late 1950s, this solution began to be interpreted physically as a region of space from which nothing can escape.

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century.

Pełniejszy materiał źródłowy / excerpt

A black hole is an astronomical body so compact that its gravity prevents anything, including light, from escaping. Albert Einstein's theory of general relativity, which describes gravitation as the curvature of spacetime, predicts that any sufficiently compact mass will form a black hole. The boundary of no escape is called the event horizon. In general relativity, crossing a black hole's event horizon traps an object inside but produces no locally detectable change. General relativity also predicts that every black hole should have a central singularity, where the curvature of spacetime is infinite. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century. In 1916, the first solution of general relativity that would characterise a black hole was found. By the late 1950s, this solution began to be interpreted physically as a region of space from which nothing can escape. Black holes were long considered a mathematical curiosity; it was not until the 1960s that theoretical work showed they were a generic prediction of general relativity. The first widely accepted black hole was Cygnus X-1, an x-ray source proposed as a black hole binary through several studies between 1971 and 1974. Black holes typically form as part of a supernova event when massive stars collapse at the end of their life cycle. After a black hole has for…

Gabriel Horn Black Hole Model in Finsler Space. The creative combination of Gabriel horn (G-horn) hyperboloid with Finsler geometry opens a new door to black holes. G-horn with finite volume but infinite surface area can characterize the frame-dragging effects of strong gravitational fields. Finsler geometry is used to describe gravitational bounce depending on velocity direction. On the smooth and inextendible manifold representing by G-horn’s inner surface, the torsion determined by Cartan connection gives rise to centrifugal force and Coriolis force to counteract gravitational collapse. The Coriolis force serves as spin-flip trigger for gravitational bounce. The entering matters are chok…
