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 ...

For more than a century the speed of light was treated as an unbreakable cosmic limit. Now physicists are revisiting that ...

Warp drives have long lived in the realm of science fiction, but the underlying physics that inspired them is very real and surprisingly precise. As researchers probe the edges of general relativity ...
