A recent publication (J.D. Anderson et. al., EPL 110, 1002) presented a strong correlation between the measured values of the gravitational constant $G$ and the 5.9-year oscillation of the length of day. Here, we provide a compilation of all published measurements of $G$ taken over the last 35 years. A least squares regression to a sine with a period of 5.9 years still yields a better fit than a straight line. However, our additions and corrections to the G data reported by Anderson {\it et al…

### Measurements of Newton's gravitational constant and the length of day

• Physics
• 2015
About a dozen measurements of Newton's gravitational constant, G, since 1962 have yielded values that differ by far more than their reported random plus systematic errors. We find that these values

### The Implications of the Sun’s Dragging Effect on Gravitational Experiments

Experimental determinations of Newton’s gravitational constant, Big G, have increased, in number and precision, during the last 30 years. There is, however, a persistent discrepancy between various

The Newtonian gravitational constant G, which is one of the earliest fundamental constants introduced by human beings, plays an important role in cosmology, astrophysics, geophysics, metrology, and

### The Origin of the Illusory Periodic Changes in the Gravitational Constant

Anderson et al. have found that experimental values for gravitational constant, G, are oscillatory with a period of P = 5.899 +- 0.062 yr and an amplitude of A = (0.001619 +- 0.000103) F, where F is

A sinusoidally time-varying pattern of the values of Newton’s constant of gravitation G measured in Earth-based laboratories over the last few decades has been recently reported in the literature. We

• Physics
• 2015
Recently we develop a model of dynamic quantum vacuum in which a given stellar object increases curvature of space and diminishes density of quantum vacuum. Motion of stellar objects is diminishing
