Discussion Overview

The discussion explores the behavior of gravity in the middle of planets and stars, questioning whether gravity converges to a singularity at the center and how it operates within the Earth's core.

Discussion Character

  • Exploratory
  • Conceptual clarification

Main Points Raised

  • Some participants inquire about the nature of gravity at the center of planets and stars, suggesting the possibility of a singularity where gravity converges.
  • One participant notes that at the center of a uniform sphere of mass, there is no net gravitational field due to equal forces acting in all directions.
  • Another participant mentions that in General Relativity (GR), being at the center of a uniform sphere results in being deeper in the gravitational well, leading to slower time compared to the surface, assuming rotation is ignored.
  • There is a playful exchange regarding the term "confurgies," with participants discussing its meaning and spelling, indicating a light-hearted tone amidst the technical discussion.

Areas of Agreement / Disagreement

Participants express curiosity and raise questions about gravity's behavior, but there is no consensus on the existence of a singularity or the implications of gravity at the center of celestial bodies.

Contextual Notes

The discussion includes informal language and playful banter, which may affect the seriousness of the technical points raised. The implications of General Relativity and the specific conditions under which gravity behaves as described are not fully explored or agreed upon.

What happens to gravity in the middle of planets and stars? Is there some sort of a singularity in the middle where gravity confurgies? Do we have any idea how gravity acts in the middle of our own planet?

confurgies?

Eh, what? :confused:

I did a Google search on the word "confurgies" and your post was the only hit! Congratulations! :biggrin:

OK, now I think I see... you meant "converges", right?

At the center of a uniform sphere of mass, there is no net gravitational field from that sphere, since there is an equal amount of force pulling in each direction.

In GR, if you are sitting at the center of a uniform sphere of mass, you have the same situation, but you are somewhat deeper in the sphere's gravitational well, so your time is slower than at the surface of the planet if we ignore rotation.

I like it. I'm adding confugies to my dictionary of acceptable spellings to join centrifical force.
 
Yes, confurgies is a keeper. Nice sounding word without a meaning.
