Discussion Overview

The discussion revolves around a proposed definition of Newtonian gravity that emphasizes the independence of the mass of the test particle and the mass creating the gravitational field, specifically in the context of circular orbits at a distance equal to the Compton length of the mass. The scope includes theoretical exploration and references to past exercises related to gravity.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant proposes a definition of Newtonian gravity based on the areal speed of test particles in circular orbits, highlighting the independence from both the mass of the test particle and the mass creating the gravitational field.
  • Another participant questions the validity of this definition and requests a reference, expressing skepticism about its originality and adherence to forum rules against personal speculation.
  • A third participant references a previous exercise related to the topic, suggesting that the current definition is a reciprocal consideration that was not previously explored.
  • There is mention of stricter rules regarding speculation in the forum compared to past discussions, indicating a shift in the community's approach to theoretical claims.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are competing views regarding the validity and originality of the proposed definition of gravity, and the discussion remains unresolved due to the closure of the thread for moderation.

Contextual Notes

The discussion references a previous exercise that may not have been fully considered in light of the current proposal, indicating potential limitations in understanding the implications of the definition. There are also noted changes in forum rules that affect how speculative ideas are treated.

Newtonian gravity is the force law such that for any mass M, the circular orbit of any test particle m at a distance equal to the Compton length of M has the same areal speed, independent of M and m.

I wonder, have you seen this sort of definition online in the literature? I guess that independency of m is used in most arguments, but independency of M is less usual.

Where are you getting this from? Do you have a reference? I'm thinking not, since you say:

Please note that personal speculation is off limits here.

the old exercise we did here
That was 20 years ago and our rules on speculation, even in the BTSM forum, are much stricter now than they were then.
