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 ...

Two physicists from the University of Queensland in Australia recently laid out a model for studying hypothetical time travel. Their work expands on what’s called the Alcubierre spacetime, first ...

The pursuit of faster-than-light travel has long been a staple of science fiction, but recent advancements in theoretical physics suggest that warp drives could one day become a reality. Scientists ...

If an Alcubierre Drive achieves a constant velocity, it's not detectable. It generates no gravitational waves and has no ADM mass. ADM stands for Arnowitt–Deser–Misner, named for three physicists. But ...

The dream of faster-than-light travel has been on the mind of humanity for generations. Until recently, though, it was restricted to the realm of pure science fiction. Theoretical mechanisms for warp ...

Late last year, it emerged that a small team of NASA researchers were working on warp drive technology in the lab. Led by Harold "Sonny" White, the team devised a variation of the Alcubierre warp ...

In a surprising paper, scientists say they’ve nailed down a physical model for a warp drive, which flies in the face of what we’ve long thought about the crazy concept of warp speed travel: that it ...
