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

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 ...

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

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 ...

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.

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 ...

A scene from the movie Gravity. In real life, gravity is always bringing us down—particularly scientists who attempt to measure gravitational force. Try as they might, physicists cannot agree on a ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

Mutual attraction: why is it so difficult to pin down the gravitational constant? (Courtesy: iStock/FrankRamspott) Two extremely precise measurements of the gravitational constant G have yielded ...

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 ...
