"Time, among all concepts in the world of physics, puts up the greatest resistance to being dethroned from ideal continuum to the world of the discrete, of information, of bits…. Of all obstacles to a thoroughly penetrating account of existence, none looms up more dismayingly than 'time.' Explain time? Not without explaining existence. Explain existence? Not without explaining time. To uncover the deep and hidden connection between time and existence … is a task for the future."

John Archibald Wheeler, Princeton theoretical physicist, responsible for reviving interest in general relativity in the United States after World War II who popularized the term "black hole", coined the terms  "quantum foam", "wormhole", and "it from bit", and for hypothesizing the "one-electron universe".
