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 ...

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 ...

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 ...

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 ...

The European Space Agency (ESA) is planning to launch two incredibly sophisticated gravity wave testing satellites in 2036 -- but they're a long, long way out. So before launching the Laser ...

Albert Einstein can rest a little easier: The first effort to measure how quickly gravity exerts its influence indicates that it more or less matches the speed of light, scientists reported Tuesday.

If you have good eyes, the smallest objects you can make out are about a tenth of a millimeter: roughly the width of a human hair. Add technology, and the smallest structures we have measured so far ...

The Lucid Gravity's first real-world range test fell far short of expectations. It performed way better on its second try, delivering over 400 miles of highway range. That's still short of its EPA ...
