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

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: ...

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 ...

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

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 ...

“All the world’s a stage…,” Shakespeare wrote, and physicists tend to think that way, too. Space seems like a backdrop to the action of forces and fields that inhabit it but space itself is not made ...

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 ...

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 ...

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 ...

A scientist studying crystal structures has developed a new mathematical formula that may solve a decades-old problem in understanding spacetime, the fabric of the universe proposed in Einstein's ...
