Etymology
In reference to celestial bodies, 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 popularisation of the term is generally credited to a 1967 lecture by physicist John Wheeler.[1] [2]
