Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and feasting on its stellar material. The observation is ...

A doomed star spiraling into a supermassive black hole has given physicists one of their clearest looks yet at how gravity ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The ...

A star’s fatal brush with a supermassive black hole can light up a quiet galaxy. When gravity shreds the star, its gas ...

Astronomers have captured an unusual ballet: a star, torn apart by the titanic forces of a supermassive black hole, exhibits rhythmic oscillations in its orbit that do not match the classical ...

A supermassive black hole was caught twisting spacetime, offering the clearest real-world evidence yet for Einstein’s frame-dragging theory.

Wormholes are one of science fiction’s favourite cheats. Need characters to cross impossible distances? Skip years of travel?

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Imagine if we could use strong electromagnetic fields to manipulate the local properties of spacetime—this could have important ramifications in terms of science and engineering. Electromagnetism has ...

Thinking of space and time as a liquid might help reconcile quantum mechanics and relativity. You have full access to this article via your institution. If spacetime is like a liquid — a concept some ...

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some ...
