Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

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 ...

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

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 ...

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 ...

A team of cosmologists in Finland and Poland have proposed that the accelerated expansion of the universe, usually explained by dark energy, may actually be the result of "Tardis regions" of spacetime ...

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 ...

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 ...

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 ...
