Noun

Etymology: Coined by physicist Robert R. Caldwell in 1998, in reference to the Star Wars movie "The Phantom Menace", in his paper "A Phantom Menace? Cosmological consequences of a dark energy component with super-negative equation of state" referring to the phantom energy menace that would lead to the Big Rip.
