A suggested space craft is presented together with sample calculations. By the way, David Lynchs 1984 film Dune seemed to suggest FTL travel was accomplished by the boosted mental powers of the Guild navigators alone via spice, but the novels are explicit there was a mechanical aspect to FTL. These predictions come from considering the force laws in a five dimensional manifold of space-time-mass.
The things would require ungodly amounts of energy to produce, not to mention exotic matter. So, always keep in mind that the laws of physics as they stand today. Answer (1 of 4): Honestly its a little hard to imagine anyone going out of their way to find alternative uses given how difficult they would be to build and run. These two predictions, taken together, present the possibility of a craft that uses the Earth's gravitational field to satisfy both requirements. Superluminal travel is more of a consideration in the feasibility of time travel and not interstellar travel, specifically travel back in time since relativistic speeds de facto result in time travel into the future (because time slows down for non-inertial observers). The potential propulsion method comes from the prediction of an inductive coupling between the electromagnetic and the gravitational fields that allows for the electromagnetic creation of a gravitational force. The prediction of transition from subluminal to superluminal speeds derives from the increased dimensionality, which alters the limiting factor of relativity to allow transition of the speed of light threshold. A previously proposed five dimensional theory of space-time-mass suggests the potential to meet both of these requirements. Secondly, there must be a propulsion method that can provide the necessary acceleration. First, a means of circumventing widely believed theoretical predictions preventing accelerating from speeds less than the speed of light to speeds greater than the speed of light. Predictions of superluminal travel must address at least two things. This argues that perhaps more serious attention might be given to suggestions or predictions of how such speeds might be obtained. Recent publications and symposia have shown an increasing number of articles discussing superluminal travel. superluminal aspects of the wire is to dispel the commonly held view that explicit WEC violation is necessary for effective superluminal travel, whereas in truth the strictures against superluminal travel are more complicated. Space exploration would be aided by superluminal travel.
