The term "black hole" is also used as a metaphor for a place that it is hard to get out of, generally containing a high concentration of something unpleasant. Ex: "The inner city is a black hole of crime and drug use." The "Black Hole of Calcutta" long predates the celestial use of the term; it was a horrible underground prison in [[Calcutta]], India.

==Are Black Holes Falsifiable?==
''Things'' cannot be judged [[falsifiable]] or non-falsifiable. The concept of being falsifiable only applies to theories or hypotheses. One can't say the unicorns are falsifiable, but the hypothesis "there are no unicorns" is. The imagined experiment would consist of finding a unicorn. If one were found, the hypothesis would be refuted. None has ever been found, but that's not germane to the question of falsifiability. Similarly, the hypothesis "there are no black holes" is falsifiable. The test would be to find one. (Many have been found, perhaps the most notable being the ones involved in the discovery of [[gravitational waves]].)
