A series of recent theoretical papers argue that some subluminal “warp-drive” spacetime designs could avoid the traditional requirement for “exotic” negative-energy matter, or at least reduce/shift ...

You know that scene in the film Contact where the “Machine” is spooling up, its three spinning rings kicking out crazy light and an electromagnetic field powerful enough to pitch nearby Navy ...

It is even possible to fit a warp drive within the equations of Einstein-and still make it practically unavailable. Over ...

A research paper proposes a fully physically realized model for warp drive. This builds on an existing model that requires negative energy—an impossibility. The new model is exciting, but warp speed ...
