A doomed star spiraling into a supermassive black hole has given physicists one of their clearest looks yet at how gravity ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The ...

Astronomers have finally captured a black hole twisting the very fabric of spacetime. This phenomenon, known as ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

A supermassive black hole was caught twisting spacetime, offering the clearest real-world evidence yet for Einstein’s ...

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 ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

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 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 ...

If you were asked to describe how you can move through the Universe, you'd probably think of all the different directions you were free to move in. You could go left or right, forwards or backwards, ...

Astronomers have finally watched a black hole twist spacetime in real time, catching the fabric of the universe itself ...
