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

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 ...

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 ...

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, ...

Using two separate tests, scientists have measured a new value for a fundamental natural quantity – G, the gravitational constant – that is slightly higher than previous experiments. Though the result ...

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help set ...

The standard model of particle physics is based in part on quantized Yang–Mills (or non-Abelian) gauge fields. The quantization of such fields leads to the important prediction that at high energy the ...
