The Most Elusive Number in Physics Just Got Even More Mysterious
TL;DR AI
2 min readKey summary
A NIST team completed a decade-long blinded experiment to measure the gravitational constant, G.
The final result did not match a 2007 French measurement and widened the gap among recent estimates.
G is one of physics’ most important constants, yet it remains notoriously difficult to measure precisely.
The disagreement may point to hidden experimental error or gaps in current understanding of gravity.
