Certain kinds of hypothetical spacetimes called warp drives have been studied by various physicists from various points of view since about 1990. In this category we collect articles related to this concept, which is not a prediction of any well established fundamental theory of physics, such as general relativity, but a theoretical speculation which might eventually lead to such a prediction.
