Scientists Opened a Sealed Envelope After 10 Years; Gravity Still Didn't Make Sense

NIST physicists spent ten years measuring the gravitational constant G in a blind experiment, repeating the 2007 BIPM experiment. The obtained value 6.67387×10⁻¹¹ m³/(kg·s²) is 0.0235% lower than the French result, a significant discrepancy for fundamental physics.

• Value of G: 6.67387×10⁻¹¹ m³/(kg·s²)
• Discrepancy with 2007 BIPM result: 0.0235%
• Data were blinded: correction kept in a sealed envelope
• Other fundamental constants are known to six or more significant digits
