A black hole is a compact region of spacetime where gravity is so strong that nothing, even light, can escape from its event horizon, and, interestingly, Einstein didn't accept this viewpoint. Now, I'm curious: who named "Black Hole"? And when? I know that John Archibald Wheeler is best known for using the term "black hole", but I heard that he adopted this term from the other physicists. Does anyone knows extra formal information about this? For example, when was the term "black hole" used for the first time in a manuscript?
Thanks you very much in advance ...
