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 Newtonian constant of gravitation -- known in the finely tuned business of metrology as 'big G' -- has come a long way since British physicist Henry Cavendish first measured the gravitational ...

Schematic diagram of four experimental devices used by the co-author’s research team. Newton’s law of universal gravitation, which describes the attractive force between two masses separated by the ...

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 ...

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 ...

Long before Galileo and Newton used superior mathematics to study a fundamental natural force, Leonardo calculated the gravitational constant with surprising accuracy. A mysterious triangle on Page ...
