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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Apollo 17 astronauts drove a moon buggy across the lunar surface in 1972, measuring subtle changes in gravitational pull with an instrument called a gravimeter. Although there are no astronauts on ...

The two stars in the nearby system ZTF J2130 are spiraling toward a catastrophic supernova. In the meantime, scientists are ...

Resources and Northern Australia Minister Madeleine King has launched the first new gravity testing site under the government's $3.4 billion ...
