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 — ...

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 ...

A group of theoretical physicists, including two physicists from the University of Groningen, have proposed a 'table-top' device that could measure gravity waves. However, their actual aim is to ...

Scientists are a step 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 ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Researchers have devised a new way to measure gravity, and they have done this by measuring the differences in atoms while they are in a superposition state. To give a bit of background on this new ...

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 ...

(Nanowerk News) Scientists are a step 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 ...

Traditionally, scientists have measured gravity’s influence on atoms by tracking how fast atoms tumble down tall chutes. Such experiments can help test Einstein’s theory of gravity and precisely ...

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 ...

This weekend, astronomers hope to measure the speed of gravity directly for the first time. They plan to capitalize on a lucky alignment of Earth, Jupiter and a group of distant stars on 7 and 8 ...
