We still don't have a more precise value for 'Big G'

A decade-long precision measurement of the gravitational constant (G) at NIST yielded a value 0.0235% lower than a previous French experiment , but the result does not resolve the uncertainty in G, which remains the least precisely known fundamental constant . Many recent measurements of big G have had slightly different values, with differences about one part in 10,000 that are too large to be explained by routine experimental errors .
