"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

As far as physicists have been able to determine, nature speaks two mutually unintelligible languages: one for gravity and one for everything else. Curves in the fabric of space-time tell planets and ...

Physicists in the US have used a tabletop experiment to rule out the existence of strong, gravitational-like forces at short length scales. Such forces, which could hint at additional space–time ...

A multi-decade analysis of a distant pulsar is affirming the longstanding notion that the gravitational constant—one of four fundamental forces of nature—is the same everywhere in the universe.

The Force is With You? You may have heard that gravity isn’t a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we’re commonly told ...

Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides. Gravity is ...
