The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest ...

Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the Universe, according to a decades-long study of a distant pulsar. This research helps to answer a ...

The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and ...

A NIST researcher has unveiled the results of a 10-year quest to measure the gravitatinal constant., which determines the strength of the attraction between two masses anywhere in the universe.

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 ...

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 ...

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 ...
