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

Standing at the doorstep of an interstellar revolution, scientists are now nearer than ever to breaking the code of warp drives a technology that can propel human civilization throughout the galaxy at ...

Traveling at warp speed is now no longer an impressive sci-fi idea, as researchers at the University of Alabama, Huntsville have suggested a new theory for a warp drive that follows the theories of ...

Physicists at the European Organization for Nuclear Research (CERN) have made a mind-bending — and rule-bending — discovery: They've measured strange subatomic particles called neutrinos traveling ...

The light echo around the star V838 Monocerotis as seen by the Hubble Space Telescope in November 2005. When I was a teenager, I was—shockingly, I know—deeply nerdy. At a science-fiction convention, I ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special relativity that includes observers moving faster than light. This fresh perspective ...

The claim that neutrinos can travel faster than light has been given a knock by an independent experiment. On 17 October, the Imaging Cosmic and Rare Underground Signals (ICARUS) collaboration ...
