Discussion Overview

The discussion revolves around the current understanding of gravity theory, particularly focusing on the equations governing gravity, their derivation, and the underlying physics. Participants explore concepts related to the nature of gravitational force, its variations, and the mathematical frameworks that describe it.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how gravity works, asking about the equations, their validity, and the source of gravitational force, including the direction of vectors and variations in gravity.
  • Another participant references Einstein's Field Equation, suggesting it as a resource for understanding gravity.
  • A participant expresses a desire for a plain English explanation of how proportionalities in gravity are derived, specifically asking for a derivation of the gravitational constant G.
  • Further resources are suggested, including various texts on General Relativity and lectures by Sean Carroll, indicating a wealth of material available for deeper understanding.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants express different inquiries and focus on various aspects of gravity theory without settling on a unified understanding.

Contextual Notes

Participants reference different sources and texts, indicating a diversity of approaches and interpretations regarding the derivation and understanding of gravitational concepts. There is an implied complexity in the mathematical and conceptual frameworks that remains unresolved.

How does it work, what are the equations, are they valid, from what matrix {}, if such, were they derived? And how high level are the physics?
Where does the force come from ie what direction has the vektors? What cause the variation in gravity that I have read about?

I read the first gravity part, just wondering, in plain english, where the proportionalities are derived from? Perhaps if you would do the thread the honor of through the circumstances themselves derivate G?

There are several GR texts on the web. Waner or t'Hooft for example. See the same Baez site for links:

There are also videos of 3 1-hour lectures by Sean Carroll.
