WASHINGTON — 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 ...

A new detection apparatus proposed by the National Institute of Standards and Technology in Boulder, Colo., hopes to explore gravity at the 100-1,000 nanometer level -- larger than atoms but many ...

Newton also used the law of universal gravitation to predict how the shape of the Earth deviates from perfect sphericity (see figure of the Earth). In the 1710s and 1720s, ...
