2-d Gravity?, A question

I have recently been reading as much as I can about all of the "hard" sciences and have come across a question that I need help in answering. First off I have an academic background in Anthropology, Psychology, and Sociology and I am at the beginning stages of deep "hard" science inquiry so please humor me. The question I have could possible be a very easy answer. I have been looking into gravity and it strikes me that its conception is very much 2 dimensional in that it is always visually displayed as a plane that objects rest on, thus leading to the mechanics of motion that our solar system is said to have. Is it actually conceived of this way? It affects 3 dimensional objects spatially, drawing them towards some point where the force is locally "originated", but that would seem to clash with the visualizations or visual models as I have thus far seen them. Would it not be better to visualize it as a kind of field of influence that draws matter in much like the core of the earth keeps the outer layers together? Sorry if this question is stupid, but I was just curious. Much thanks to anyone who can help!

gravity is one of those things that is hard to explain and most things describe it or mention it, however it is defined by string theory to be a particle that is in constant motion from one plane to another sort of creating this suction like hole which is why they describe it as being like placing a heavy object on a bed and placing smaller objects around it. although i just thought of it where it would create negative space in which objects r attracted by the flow of space..........makes no sense does it ...........ill work on it though it makes sense to me

Gravity is a 3 dimensional force, as you understand. The flat examples, are just ways to visualize this easier.

Gravity (in the Newtonian model) is a central force, so in a system dominated by one huge mass, a much smaller mass will be constrained to lie in a plane dictated by it's momement of inertial relative to the central mass. Thus each planet in the solar system lies in it's own plane. The fact that the 9 planets approximately share the same plane (the ecliptic) is an observation which is used by most theories of plantary genesis.

There are many objects in the solar system (some man-made) that are not in the plane of the ecliptic.

In a system with 3 masses which are relatively non-negliable, only very special initial conditions lead to a planar solution. (The 3-body problem for Newtonian gravity is difficult to address analyticaly, but interesting.)

http://www.ids.ias.edu/~piet/publ/gmbp.html "The Gravitational Million-Body Problem" is a fun read based on the introductory chapters.

I suppose, the gravity is manifestation of hypothetic 1D supergravity force, which can be derived just using laws of geometry for diffusion of system of randomly moving vacuum density fluctuations like entropic process.



The 2D picture simplifies the understanding of such concept, although it's evident, such mechanism works just in the single dimension too. It's simply process of leveling of vacuum density concentration.

According to the Einstein Theory; Gravity bends Light. I think that the light can't be deflected one-sidedly. It should also affect back the gravity field. Beams of light will loosen the gravity field to the orthogonal direction slightly. And huge amount of beams of light or emissions will shove away the gravity field in a thin-depth disk.

Then I have defined the Two or One Dimensional Galaxy System. For the two dimensional universal gravity equation like a spiral galaxy. It can be called "New2ton's equation".

F can be transformed into F = G'Mm/r
Here G' = the two dimensional universal gravity constant
F = G'Mm/r G'Mm/r = mv*v/r
v = const = root( G'M )
M ? M(<r) ∝ v*v = constant for each galaxy

For the one dimensional universal gravity equation for a barred spiral galaxy; It can be called "New1ton's equation".

F can be transformed into F = G"M(<r)m ; ( if >r then F = constant )
Here G" = the one dimensional universal gravity constant
F = G"M(<r)m G"M(<r)m = mv*v/r
M(<r) = 2M'r ( where <r ) v*v = 2G"M'r*r v = root(2G"M')*r
Here M' is distributed uniformly in the cylinder.

Then I can explain that stars in the galaxy can move around the center of the galaxy with the same velocity, not related to the distances from the center. And now I don't have to assume the existence of the "Dark Matter" against the galaxy rotation problem. This means that in a barred spiral galaxy the velocity fields are consistent with rigid body rotation. Arms are made of overflows from the cylinder ends while the strong emission deprives the mass of the cylinder and makes it shorter in length little by little. A shorter and a little bit lighter cylinder should have a slower rotation speed than overflowed stars. Overflowed stars are going ahead of the cylinder rotation with the velocity of
v = root(2G"M')*r , where there is only a weak three and two dimensional gravity potential and where are a lot of interstellar gas and materials which interfere their movings. Most of them take the same elliptical orbit. While traveling halfway around, they are diffused and slow down, and then a small amount of remainings are absorbed into the another end of the cylinder with a tremendous speed because the gravity is so strong there that I can't see the fallings. Observations reveal that the velocity of rotation of barred spiral galaxy is somehow flat or a little increasing by the distance from the center. It is because the observed velocity is the average of stars both in the cylinder and in arms.

These are verified by Schrodinger equation. The spherical harmonics are the angular portion of the solution to Laplace's equation in spherical coordinates where azimuthal symmetry is not present.
