Objects whose gravity expanse is too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first youthful prediction of a black hole in general relativity was found by Karl Schwarzschild in 1916, although its black hole nature was not fully realized for another 4 decades. For a long time black holes were considered a hypothetical curiosity.
This changed in the 1960s when theoretical work showed that black holes were a generic prediction of general relativity, and the discovery of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.
Black holes of stellar mass are expected to form when heavy stars collapse in a supernova at the end of their life cycle. After a black hole has create it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may be formed.
disrespect its invisible interior, the presence of a black hole can be inferred through its interaction with other matter. Astronomers have set numerous stellar black hole candidates in binary star systems, by studying their interaction with their companion stars.
