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 ...

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 ...

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 ...

Physicists have made the first precise measurement of Newton’s universal gravitational constant to use vibrating beams 1. Although the technique is not yet as precise as others, it could eventually ...

The measurement of the Newtonian gravitational constant, G, remains one of the most challenging pursuits in experimental physics. A variety of techniques have been devised over the past two centuries, ...

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 ...

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 ...
