Big G Remains Elusive as a Decade of Gravity Tests Clash with CODATA
TL;DR
After a decade of cross‑Atlantic replication led by NIST, the new measurement of the gravitational constant G disagrees with both the 2013 BIPM result and CODATA’s current value, highlighting that Big G is still the least precisely known fundamental constant and that the true value remains unresolved despite improved methods (including a blinded measurement to reduce bias).
