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

Click For Summary

Discussion Overview

The discussion revolves around the variability of the gravitational constant (G) and its implications in science. Participants explore the reasons behind differing measurements of G, referencing historical data and questioning the validity of these variations.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants question the implications if G is not a constant, suggesting significant consequences for scientific understanding.
  • One participant references an article discussing the variability in measurements of G, noting that when a periodicity is considered, laboratory measurements align within experimental error limits.
  • Another participant presents historical data showing a 1.1 percent difference in average values of G from 1973 to 2010, questioning why this variability is not widely accepted as evidence of a non-constant G.
  • Several participants emphasize the need for sources when making claims about the variability of G.
  • One participant dismisses a referenced figure, suggesting that their contributions should not be taken seriously in the context of physics.
  • A moderator closes the thread, indicating that the discussion is centered on non-scientific claims.

Areas of Agreement / Disagreement

Participants express disagreement regarding the validity of claims about the variability of G, with some questioning the scientific basis of these claims and others suggesting that the variability is a legitimate topic of discussion. The discussion remains unresolved.

Contextual Notes

Limitations include a lack of consensus on the sources of variability in G and the dependence on specific measurements and interpretations of data.

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.
