Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely ...

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 ...

One of the biggest challenges to prepare people and equipment to operate on the moon is gravity. Gravity on the lunar surface is one-sixth of what we experience on Earth. All personnel and equipment ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

On April 20, a satellite conceived in the 1960s to test two aspects of Einstein’s general theory of relativity finally roared into space from Vandenberg Air Force Base in California. Aside from two ...
