# The Dual Nature of Gravity

I thought of the dual nature of gravity, comparing it to an outside -in in tree trunk.

looking at that image with its empty interior "cavity" it occurred to me that the Sequoia analogy is a vivid one. gravity herding mass from the outside in* corralling it into two rotating fields, one with dust, planets, the other stars. Bit unlike a tree trunk, leaving no substance in the center not even gravity, having drawn all into the ring and star masses.
* love to mix metaphors.

Everyone, with me now: What do you mean, nebel? Gravitational potential? Gravitational force? Gravitational field strength?

Well, as a said, to avoid an oversize blowback, and teach this old dog to learn new tricks, please contribute by using my assertion (not here please, but on a clearer thread) and answer using a), b), c) in other words your definitions that you understand. 3 choices of answers. and my postings will be clearer in the future. thank you. (of course let not your desire to have me stop posting stop you)

Take an object of typical density, and say, 4000 miles in radius.
Pick a point inside it, say, 3000 miles from the centre.
The gross gravitational force is the sum of the gravitational force of every single atom everywhere in the body.
It just happens that some of those vectors (magnitude AND direction) point in opposite directions (which result in a lower net gravity).

The gross effect of every atom is accounted for. They're just competing - resulting in a smaller net force, not a smaller gross force.

Talking of the gravitational force, when two or more of those atoms are compared, seen together, is the gravitational force between them cancelled or are they still attracted to each other while being held apart by the structural strength of the other forces? is the net force you identify the free, unopposed vectors outside the surface, even the ones that come from the atoms near the opposite surface? Only inside is any gravity opposed temporarily, because the same gravitational force component emerges from the surface with its appropriate strength, as if it never had been "opposed", "competing" in the interior. Thus,
The full, gross gravity force exists only in the outside, the "lower net gravity)" on the inside.
for consideration.
Inside gravity force is opposed by other forces and the structure.

obviously gravitational field strength

because origin's graph from Wikipedia was showing the strength of the force of gravity, but field strength is the better word, because the strength is there wether a force is acting or not.
Thank you for clearing concept that in my mind. but
That definition was always implied by the use of the small case "g" in the graphs.

What other forces oppose inside gravity force ?

What other forces oppose inside gravity force
They are still working on unifying all the forces, but
The pressure that "gravity" the force of the field exerts, is generating in/on a body is opposed by the forces that hold atoms together and apart. in addition by radiation pressure like inside in our Sun.
here is the latest graph and equation for "gravity"(gs) outside a body :

Still can't see your images.

Still doesn't matter - because you're

still spewing word salad.

Unwatch.
