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 ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

WASHINGTON (ISNS) -- Scientists know how gravity works at big distances -- the inter-planetary or inter-stellar range -- but does it work the same way at the inter-atomic range? A variety of tabletop ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

Gravity is the weakest of the fundamental forces, but it’s the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...

General relativity is the basis of our understanding of gravity. But twenty-first-century work in cosmology and particle theory strengthens the belief that it is an incomplete description. Although ...

Phones are gradually replacing a large number of everyday items and the latest household gadget under threat is the weighing scale. Huawei recently unveiled a phone that can be used to weigh small ...
