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

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

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

Astronomers have finally captured a black hole twisting the very fabric of spacetime. This phenomenon, known as ...

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 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 ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. Experts warn the internet will go down in a big way — and you'd better be ready ...

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

The biggest lesson from Einstein's general theory of relativity is that space itself isn't a flat, unchanging, absolute entity. Rather it's woven together, along with time, into a single fabric: ...

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 ...

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 ...

A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole ...
