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 ...

For more than half a century, faster than light travel has lived in the realm of television scripts and paperback science fiction. Now a cluster of theoretical breakthroughs is forcing physicists to ...

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 ...
