Progress in measurement of gravitational constant?

Click For Summary
SUMMARY

The gravitational constant (G) was measured using atomic interferometry in 2014, but recent discussions indicate that the proposed 5.9-year measurement cycle has been largely discredited due to selective measurement choices and misattributed dates. Corrections to these points have rendered the cycle less plausible. Current efforts to improve measurements of G are ongoing, as highlighted in a recent article by the American Physical Society (APS).

PREREQUISITES
  • Understanding of atomic interferometry techniques
  • Familiarity with the concept of the gravitational constant (G)
  • Knowledge of scientific measurement methodologies
  • Awareness of the American Physical Society's contributions to physics research
NEXT STEPS
  • Research advancements in atomic interferometry for gravitational measurements
  • Explore the implications of the gravitational constant in modern physics
  • Study the methodologies used in the APS article regarding measurements of G
  • Investigate the historical context and controversies surrounding measurements of G
USEFUL FOR

Physicists, researchers in gravitational studies, and anyone interested in the precision measurement of fundamental constants.

I read that in 2014 the gravitational constant was measured by atomic intereferometry. Now I read that they speculate that measurements of G are in correlation with 5,9 years cycle.

But, when we can expect new measurements of G? Are they in preparation?

The paper which suggested the 5.9 year cycle has been mostly discredited due to the fact that the choice of measurements was quite selective and the dates assigned to some of the measurements were the date of publication rather than the date of the measurement. After those points were corrected the cycle is much less plausible. This is mentioned in the Wikipedia article on the gravitational constant, https://en.wikipedia.org/wiki/Gravitational_constant

Here's a recent American Physical Society (APS) article about trying to find better ways to measure "big G":
