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 ...

A team of physicists has discovered that it’s possible to build a real, actual, physical warp drive and not break any known rules of physics. One caveat: the vessel doing the warping can’t exceed the ...

Einstein’s general theory of relativity is a tool kit for solving problems involving gravity that connects mass and energy with deformations in spacetime. In turn, those spacetime deformations ...

Anyone who grew up obsessed with Star Wars will know the thrill of seeing Han Solo and Chewbacca launch the Millennium Falcon into hyperspace for the first time. In the films, hyperdrive engines allow ...
