Dubbing these “closed timelike geodesics” (CTGs), Ralph and Sajeendran explain in the paper: “Such a CTG would be ideal for ...

Scientists said the warp drive, once considered to be purely hypothetical, is slowly edging toward legitimate physics.

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 ...

Star Trek's iconic warp drive, once pure science fiction, is now inspiring real-world astrophysicists. Scientists are ...

Warp drive concepts suggest a ship could ride a bubble of space-time faster than light without breaking relativity.

(via PBS Space Time) The vacuum of space is a chaotic sea of quantum fluctuations. Some have said that this vacuum energy can be harvested to build our future starship engines, or manipulated to build ...

You know that scene in the film Contact where the “Machine” is spooling up, its three spinning rings kicking out crazy light and an electromagnetic field powerful enough to pitch nearby Navy ...

To construct a warp drive, we'd need 10 times more negative energy than all of the positive energy in the universe. When you purchase through links on our site, we may earn an affiliate commission.

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks. When it comes to space travel, Albert Einstein's theory of relativity is a major ...
