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 ...

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 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 ...

For the first time, astronomers have directly observed a spinning black hole bending space and time, as predicted in Albert ...

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 ...

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 ...
