If the gravitation has very very tiny deviation from inverse square law！

Click For Summary

Discussion Overview

The discussion revolves around the potential implications of a tiny deviation from the inverse square law of gravitation on the stability of the solar system. Participants explore whether such a deviation could be noticeable on Earth and the time frame in which it might be observed.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions if a tiny deviation from the inverse square law would lead to instability in the solar system and how long it would take for people on Earth to notice it.
  • Another participant asserts that there is indeed a tiny deviation, but argues that it does not significantly impact the stability of planetary orbits compared to other factors.
  • A participant challenges the existence of any deviation from General Relativity (GR) in this context.
  • There is a suggestion that the discussion may relate to the pioneer anomaly, which could be a relevant example of gravitational deviation.
  • A participant proposes merging this thread with another discussion in the General Physics section, indicating a potential overlap in topics.

Areas of Agreement / Disagreement

Participants express differing views on the existence and significance of deviations from the inverse square law, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

Some assumptions regarding the nature and implications of gravitational deviations are not fully articulated, and the discussion does not clarify the specific deviations being referenced.

If the gravitation has very very tiny deviation from inverse square law！our solar system became unstable? If so ,how long people on the Earth can notice it?

It does have a tiny deviation, and it doesn't make much difference. The planets have a much larger effect on perturbing the Earth's orbit than relativistic corrections.
 
What deviation from GR did you have in mind? I don't see any.
 
Perhaps Phrak is talking about the pioneer anomaly?
