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 ...

Inspired by Gene Roddenberry’s Star Trek, physicist Miguel Alcubierre set out to transform one of the cornerstones of science fiction iconography, the Warp Drive, into reality. But is it even possible ...

Add Yahoo as a preferred source to see more of our stories on Google. Aided by the gravitational pull of Venus and the sun, NASA's Parker Solar Probe became the fastest man-made object in history when ...

The future may look like Star Trek predicted, according to a new model. Scientists have embarked on an endeavor to prove the possibility of warp drive engines outside of science fiction. This means ...

Dr. Richard Obousy describes an advanced space-propulsion concept based on modifying the local cosmological constant to facilitate an expansion/contraction of spacetime around a spacecraft to create ...

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 ...

Arvix – Metamaterial-based model of the Alcubierre warp drive by Igor I. Smolyaninov of the University of Maryland. Alcubierre imagined a small volume of flat spacetime in which a spacecraft sits, ...

Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of “controlled closed timelike curves.” Though far out, ...
