Modern measurements of G

As a response to my inquiry someone offered the following papers as modern experimental values of G:

Measurement of Newton’s Constant Using a Torsion Balance with Angular Acceleration Feedback Jens H. Gundlach and Stephen M. Merkowitz

A rotating torsion balance experiment to measure Newton’s constant J H Gundlach

New technique for measuring Newton’s constant G J. H. Gundlach, E. G. Adelberger, B. R. Heckel, and H. E. Swanson

The value of G presented in these papers is worthless. These are not scientific experiments. Gundlach and Co. built an oscillator with a given period and measured its period. Since the given period was selected to give the known value of G their experiment could not have given any other value but the known value of G. Since when such definitions with a gadget are called an experiment? The papers entered physics literature on the authority of the physicists who published these papers. This is called scientific fraud.

The Cavendish experiment has been duplicated hundreds, or maybe thousands, of times. The experiments described in the above papers were never duplicated and cannot be duplicated. They are in fact representative specimens revealing the corrupt state of physics today. In physics what counts is authority. Gundlach and Adelberger have enough authority to push their opinions, and these are untested opinions of Gundlach and Adelberger, nothing more, into physics canon. While the same physicists teach their students that physics is an experimental science and experiments are carefully verified by hostile parties. What a racket physics is!

Whatever its faults, Cavendish’s experiment can be duplicated, therefore it is science. The above papers describe the authors’ opinions and have never been duplicated. They should be retracted.
