The Gravitational Constant may not be Constant: Correlation of Gravitational Constant Measurements with Ambient Gravitation

There is a long history of measuring the gravitational constant starting with Henry Cavendish in the 1700’s,[1], and in the last 15 years there has been a focused on refining the value with more modern technology, and precision instrumentation. Unfortunately the value is hard to pin down, and as the error bars of the various experiments at labs around the world get smaller the values are not the same and even the error bars are not overlapping. This paper evaluates the relation between the most precision measurements over the last 15 years, and the ambient gravitation at the location of the measurement. Although there may be some errors in the exact value of the ambient gravitation due to the exact location of the lab making the measurement, the errors are not significant enough to make a difference in the conclusion. There is a definite relationship between the measured gravitational constant and the ambient value of the background gravitation. This paper presents the data illustrating the correlation.
