A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

"Warp drives" used by super-advanced alien civilizations may create specific space-time ripples in their wake that we can spot from Earth, a new paper argues. However, the jury is still out on whether ...

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

If humanity ever wants to escape the solar system, we’re going to need a faster-than-light engine. Enter: the warp drive. While such a drive pushes the limits of known physics, a new study ponders ...

If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal ...

In an interstellar race against time, astronomers have measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star–just before it vanished […] ...

The Milky Way is warped, possibly as the result of a collision with another galaxy billions of years ago. Studying this warp could reveal more about the structure of our galaxy's hidden matter. When ...
