ИСТИНА

The Newtonian gravitational constant G is one of the fundamental constants of nature. Accurate knowledge of this constant is not only of considerable methodological interest, but is also important due to the key role which it plays in gravity, cosmology, geophysics. To date, more than 200 experiments of the G measurement have been performed, including the experiments of Moscow University and Huazhong University of Science and Technology, but an accuracy of G value increases very slowly, only about 10 times in a century. Two independent experiments for G measurement have been performed at Huazhong University of Science and Technology (China). Two values of the gravitational constant with relative uncertainties of 11.6×10-6 were obtained in these experiments.
