Cause of Gravity Force: Explaining Monopolar Attraction

Click For Summary

Discussion Overview

The discussion centers around the nature of gravity, particularly questioning why it is considered monopolar compared to electromagnetic forces, which are described as bipolar. Participants explore the implications of various models, including Einstein's rubber sheet analogy and the geometric interpretation of gravity in General Relativity.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the monopolar nature of gravity, contrasting it with electromagnetic forces, and suggests that a hierarchy of forces might explain gravity.
  • Another participant references General Relativity, stating that gravity is a result of the curvature of space-time, but acknowledges that the deeper reason for matter's behavior in this context remains unanswered.
  • A third participant urges a focus on established physics, implying that some analogies may not accurately represent gravitational phenomena.
  • A later reply critiques the rubber sheet analogy as misleading and suggests looking for other discussions and resources on the topic.

Areas of Agreement / Disagreement

Participants express differing views on the validity and implications of the rubber sheet analogy, with some advocating for its relevance while others challenge its accuracy. The discussion remains unresolved regarding the nature of gravity and the appropriateness of various models.

Contextual Notes

There are limitations in the assumptions made about the rubber sheet analogy and its implications for understanding gravity. The discussion also highlights the dependence on interpretations of General Relativity and the unresolved nature of the questions posed.

Force is naturally associated with something acting on anything. Eletromagnetic forces are bipolares, i.e., charges are of opposite signals to atract one another. Why gravity is monopolar ? The einsteins elastic rubber example imply on a kind of hyerarchy of forces, so, it would possible that such hyerarchy of forces possibly causes what we know as gravity ?

General Relativity theory describes gravity as the geometry of space-time and as Wheeler said:

Matter tells space-time how to curve and space-time tells matter how to move.

Why matter likes to travel space-time geodesics can't be answered until perhaps we have a theory of everything when all will be revealed until we find something that isn't...

I like the old story of the Earth being supported in the heavens by sitting on the back of a giant. The giant? He's standing on a turtle. The turtle? It's standing on another and its turles all the way down...
 
Let's keep it to actual physics, please.

You're taking that rubber sheet analogy too seriously. It doesn't "imply" anything because it's not really how gravity works, it's just a generally misleading analogy.

You might try searching this forum for other discussions of the rubber sheet analogy, as well as poster A.T.'s videos and animations of gravity at work.
