Black hole drive in the film "Event Horizon" Cheesy movie, right? A lot of fun though. For those who don't know, there is a starship in the film called the Event Horizon, which utilizes an artificial black hole drive/engine in order to allow it to fold space, although it's probably more accurate to say that it's an artificial worm hole. Two questions: 1) Would this actually work? Or would the artificial worm hole have to be large enough for the entire ship to fit through? In the movie it's only about the size of a car. 2) Would it be more efficient if the source of power were an artificial sun, instead? I seem to remember reading somewhere about a fictional starship that used such an engine.
