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 ...

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

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

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 ...

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: ...

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 ...

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

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 ...

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 ...

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 ...
