In order to conquer these huge distances and times for interstellar travel, superluminal speeds become indispensable. If one considers the use of general relativity in the context of interstellar space travel rather than special relativity, then we no longer think of the problem in terms of a propulsion theory, but rather a navigation theory, such as a wormhole engineering of space-time itself. This notion becomes indispensable for the problem if interstellar travel, where cruising ranges are on the order of light-years. Practical interstellar exploration must therefore solve both the propulsion and the navigation problem. In this chapter, several different concepts involving warp drive navigation are described.
