Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

In the quest to measure the fundamental constant that governs the strength of gravity, scientists are getting a wiggle on. Using a pair of meter-long, vibrating metal beams, scientists have made a new ...

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn't sure he wanted to know the secret number that lay ...

The gravitational constant G determines the strength of gravity—the force that makes apples fall to the ground or pulls the Earth in its orbit around the sun. It is part of Isaac Newton's law of ...

Newton's law of universal gravitation, which describes the attractive force between two masses separated by the distance, is one of the greatest achievements in the 17th century. The strength of this ...

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. The pursuit was more or ...
