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

- Big G, the gravitational constant, measures gravitational force or spacetime curvature.
- It's known roughly but with variations (about 1 part in 10,000 difference between measurements).
- Gravity is the weakest fundamental force, making precise lab measurements difficult due to Earth's gravitational noise.
- Scientists have struggled to measure it precisely for over 200 years.
- A recent NIST study replicated a divergent measurement, adding a data point without resolving discrepancies.
