Hyperfast Interstellar Travel in General Relativity
arXiv:gr-qc/9511068 · doi:10.1103/PhysRevD.57.4760
Abstract
The problem is discussed of whether a traveller can reach a remote object and return back sooner than a photon would when taken into account that the traveller can partly control the geometry of his world. It is argued that under some reasonable assumptions in globally hyperbolic spacetimes the traveller cannot hasten reaching the destination. Nevertheless, it is perhaps possible for him to make an arbitrarily long round-trip within an arbitrarily short (from the point of view of a terrestrial observer) time.
The final version, close to (but better than) what will be published in Phys. Rev. D. The explanatory part is made more detailed
