词源
In reference to the physical concept (region of spacetime with extreme gravitational pull), physicist Hong-Yee Chiu attributed the term to his colleague Robert H. Dicke, who stated around 1960–1961 that the objects were like the Black Hole of Calcutta. The first known usage in print was by journalist Ann Ewing in 1964. Widespread popularization of the term is generally credited to a lecture in 1967 by the physicist John Wheeler.
