This is the first time that disk-jet co-precession has been clearly observed in a black hole system, which is truly exciting, ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Astronomers have seen spacetime itself wobble near a spinning black hole for the first time. The discovery, revealed during a star’s destruction, confirms a major prediction of Einstein’s theory of ...

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 ...

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 ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. House fails to override Trump's ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS Space ...

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 ...
