What is the reason that the Gravitational Constant (G) varies?

Click For Summary
SUMMARY

The gravitational constant (G) has been observed to vary, with laboratory measurements between 1973 and 2010 showing a range from 6.6659 to 6.734, indicating a 1.1 percent difference. This variation is significant, exceeding 40 times the estimated experimental errors. The discussion highlights skepticism regarding the variability of G, particularly in the context of scientific credibility and the sources of such claims. The implications of a non-constant G raise questions about foundational principles in physics.

PREREQUISITES
  • Understanding of gravitational physics
  • Familiarity with experimental error analysis
  • Knowledge of scientific measurement techniques
  • Awareness of the scientific method and peer review
NEXT STEPS
  • Research the implications of variable gravitational constants in theoretical physics
  • Study the periodicity of gravitational measurements and its significance
  • Explore the methodologies used in measuring G and their associated errors
  • Investigate the credibility of sources in scientific discussions, particularly in physics
USEFUL FOR

Physicists, researchers in gravitational studies, science communicators, and anyone interested in the foundational principles of physics and measurement accuracy.

TL;DR
As the methods of measurement became more precise, the disparity in measurements of G by different laboratories increased, rather than decreased.
If G really not a constant then what are the implications in science?

Between 1973 and 2010, the lowest average value of G was 6.6659, and the highest 6.734, a 1.1 percent difference. The difference between recent high and low values is more than 40 times greater than the estimated errors.
what is the reason we don't believe it is variable?

On PF, we don't make statements like that without citing the source.

What is your source that says this variation?

Rupert Sheldrake should not be taken seriously, especially not in the field of physics.

Since this whole thread is about non-science, thread closed.
