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 ...

A painting of Sir Isaac Newton by Sir Godfrey Kneller, dated to 1689. A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the ...

Physicists have used the quantum nature of matter to obtain a highly precise value for the universal gravitational constant, the 'big G' that appears in Isaac Newton's law of how gravity pulls ...

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 ...

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 ...

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 ...

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 ...
