------------------------------------------------------ Uncertainty in the Universal Gravitational Constant G. ------------------------------------------------------
How's about this then? 8-) At least they admit it - especially the Russkies. ====================================================== http://www.npl.washington.edu/eotwash/gconst.html ------------------------------------------------------ Recently the value of G has been called into question by new measurements from respected research teams in Germany, New Zealand, and Russia. The new values disagree wildly. For example, a team from the German Institute of Standards led by W. Michaelis obtained a value for G that is 0.6% larger than the accepted value; a group from the University of Wuppertal in Germany led by Hinrich Meyer found a value that is 0.06% lower, and Mark Fitzgerald and collaborators at Measurement Standards Laboratory of New Zealand measured a value that is 0.1% lower. The Russian group found a curious space and time variation of G of up to 0.7% The collection of these new results suggests that the uncertainty in G could be much larger than originally thought. This controversy has spurred several efforts to make a more reliable measure of G. ====================================================== Cheers Grimer
