Recent measurements of the gravitational constant as a function of time

Abstract

A recent publication (J.D. Anderson et. Al., EPL 110, 1002) found 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 sinusoid 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 et. al. significantly weaken the significance of the reported correlation.
