What is mass? It seems like a synonym for weight, but that isn’t quite right. Weight is how we measure the pressure that gravity exerts upon things. But mass? Mass is the actual presence of an item — ...

Learn how to calculate the spin rate required for a spacecraft to generate artificial gravity at half of Earth’s gravity! In this video, we break down the physics behind rotational motion, centripetal ...

Scientists are closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force works in ...

Extremely cold atoms have been used to measure gravity more precisely than we thought possible, beating a limit that stems from quantum weirdness. Ultracold atoms are some of the most sensitive force ...

On the very smallest scale, the world is mysterious and counter-intuitive. At this level, things simply don't work the way you'd expect them to, and quantum mechanics is our best attempt at applying a ...

The European Space Agency (ESA) wants to land a tiny mobile phone-sized satellite on an asteroid to measure its gravity. Thus, measuring the gravity will be no easy task, as the gravity on a body such ...

Quantum scale gravity has long been a mystery to physics, but things could be starting to change. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
