The measurement of Newton's constant G has a relatively long history. However, G is the fundamental physical constant with the largest uncertainty of any fundamental physical constant up to now. To resolve the discrepancies in the value of G, a measu

In theories where a scalar field couples nonminimally to gravity, the effective gravitational “constant” becomes dependent on the value of the scalar field. This note first gives a brief review on how the cosmological evolution provides a dynamic

General Relativity (GR) is consistent with a wide range of experiments/observations from millimeter scales up to galactic scales and beyond. However, there are reasons to believe that GR may need to be modified because it includes singularities (it i

We created and analyzed a citation history of papers covering measurements of Newton’s constant of gravity from 1686 to 2016. Interest concerning the true value of the gravitational constant was most intense in the late 90s to early 2000s and is ga

Three decades of careful experimentation have painted a surprisingly hazy picture of the constant governing the most familiar force on Earth.

A modification of general relativity is presented in which Newton's constant and the cosmological constant become a conjugate pair of dynamical variables.

We have developed a new method to determine the gravitational constant. This method severely reduces the sensitivity to the leading sources of error in previous torsion balance measurements: it is mostly free of uncertainties due to anelastic torsion
