Through this crack in the cosmic egg steps Herbert, a Stanford physicist and author of Quantum Reality, who summarizes clearly current speculation and theory about. We conclude that the weak energy condition alone is not sufficient to prevent superluminal travel in asymptotically flat spacetimes. On the contrary, it seems to indicate that certain superluminal or FTL effects would permit us to re-experience the past: time travel would become a reality, not science fiction. Jul 31 11 at 8:50 begingroup Karsus: relativity does not prohibit it at all and tachyonic solutions can be found e.g. The CTCs under investigation do not need to enter the wires’ singularities, and can be confined to regions that are weak-field: this means that if these wires were physically possible, they would present causality problems even in nonsingular, energetically realistic regions of the spacetime. begingroup This is a hypothetical question as relativity prohibits real superluminal travel. This spacetime is asymptotically flat: it becomes a Minkowski spacetime a finite distance away from each of the wires.

A new research paper authored by an American physicist offers a potential blueprint for superluminal travel.
Superluminal travel free#
We present a model spacetime which contains two wires which are free to move relative to each other. Spaceships zipping at the speed of light or faster are a staple of science fiction. We also demonstrate how the existence of such ‘wires’ could create CTCs. Our purpose in presenting the 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. (The singularities themselves are not well-defined, so the WEC is undefined there, but it is never explicitly violated.) Parallel to the wire, ‘effective’ superluminal travel is possible, in that the wire may be used as a shortcut between distant regions of spacetime. Empirical confirmation followed soon afterward, and the first working prototype of an FTL drive was constructed in 2114. The weak energy condition (WEC) is preserved in all well-defined regions of the spacetime. Although long theorized, superluminal travel did not become a practical reality until Ilya Markov codified the unified field theory (UFT) in 2107. Each wire may be straight-line singularity or a ring singularity. We examine closed timelike curves (CTCs) and ‘effective’ superluminal travel in a spacetime containing naked line singularities, which we call ‘wires’.
