Scientists are a step closer to unraveling 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 that ...

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 ...

Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...
