Abstract. Implementation of faster-than-light (FTL) interstellar travel via traversable wormholes, warp drives, or other spacetime modification schemes generally requires the engineering of spacetime into very specialized local geometries. The analysis of these via Einstein’s General Theory of Relativity (GTR) field equations plus the resultant equations of state demonstrate that such geometries require the use of “exotic” matter in order to induce the requisite FTL spacetime modification. Exotic matter is generally defined by GTR physics to be matter that possesses (renormalized) negative energy density, and this is a very misunderstood and misapplied term by the non-GTR community. We clear up this misconception by defining what negative energy is, where it can be found in nature, and we also review the experimental concepts that have been proposed to generate negative energy in the laboratory.

INTRODUCTION

It was nearly two decades ago when science fiction media (TV, film and novels) began to adopt traversable wormholes, and more recently “stargates,” for interstellar travel schemes that allowed their heroes and heroines to travel throughout our galaxy. Little did anyone outside of relativity physics know but that in 1985 physicists M. Morris and K. Thorne at CalTech had in fact discovered the principle of traversable wormholes right out of Einstein's General Theory of Relativity (GTR, published in 1915). Morris and Thorne (1988) and Morris, Thorne and Yurtsever (1988) did this as an academic exercise, and in the form of problems for a physics final exam, at the request of Carl Sagan who had then completed the draft of his novel Contact. Sagan wanted to follow the genre of what we call science “faction,” whereby the story’s plot would rely on cutting-edge physics concepts to make it more realistic and technically plausible. This little exercise ended up becoming one of the greatest cottage industries in general relativity research – the study of traversable wormholes and time machines. Wormholes are hyperspace tunnels through spacetime connecting together either remote regions within our universe or two different universes; they even connect together different dimensions and different times. Space travelers would enter one side of the tunnel and exit out the other, passing through the throat along the way. The travelers would move at <= c (c = speed of light) through the wormhole and therefore not violate Special Relativity, but external observers would view the travelers as having traversed multi-light year distances through space at FTL speed. A “stargate” was shown to be a very simple special class of traversable wormhole solutions to the Einstein GTR field equations (Visser, 1995; Davis, 2004).
