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

Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...

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

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

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

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to understanding the Universe, there are a few things ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. Fans walk out of Wizard of Oz Christmas show: 'It was atrocious' ...

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 ...

Your location in this Universe isn't just described by spatial coordinates (where), but also by a time coordinate (when). It is impossible to move from one spatial location to another without also ...
