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 ...

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 ...

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 ...
