PITTSBURGH (KDKA) -- We have discussed gravity in a couple different experiments. This time, I am going to show you something that may seem almost impossible to do. Then we will discuss how it works, ...

Upcoming experimental tests of gravity’s quantumness aim to resolve one of the biggest questions in physics, but theorists ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

In 2007, a peculiar gravity signal was detected from deep within Earth, suggesting rapid changes near the planet’s core. This ...

Such gravity variations are often caused by variations in the ... the study was that Earth is complex and that different ...

We probably think we know gravity pretty well. After all, we have more conscious experience with this fundamental force than with any of the others (electromagnetism and the weak and strong nuclear ...

About a century ago, Albert Einstein amazed the world with his groundbreaking theory of relativity, and ever since he shared this profound understanding of gravity and spacetime, physicists everywhere ...

Einstein’s general theory of relativity is a tool kit for solving problems involving gravity that connects mass and energy with deformations in spacetime. In turn, those spacetime deformations ...

The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what ...
