Just for personal pleasure I've decide to delve into the works of einstein such as space-time and other theories that try to explain everything. I believe that if I truly want to understand it I'm going to have to figure it out by making my own conclusions on information that I find or have hypothesized.

Please someone answer these questions for me, as I have have no idea where to look for the answers (tried google but it didn't help). They're pretty important to what I'm looking at now and I do not have the theoretical knowlege or the means to observe this information.

First I need to know the mass and density of planets, stars or other celestial bodies (as many and as exact as possible). I also will need the planet's (or whatever) radius to their surface, and radius to the edge of their field of gravity.

One other thing. You know that experiment where you use liquids of different density, put them in a container and let them separate? The heaviest/ most dense liquid end up on the bottom. You could use more than two liquids too and they will always arrange themselves most dense to least dense with the most dense liquid closest to the source of gravity and a clear partition between each liquid that is perpendicular to the force of gravity.

My question is how would the liquids arrange themselves if they were in space far from the gravitational pull of any celestial mass. My prediction is that the heaviest particle will eventually be forced into the center of the container forming a sphere. The other liquids will form layers around the sphere with the next most dense liquid as the first layer around the original sphere of the most dense liquid. the least dense material will evenly distribute itself between the surface of the sphere and the walls of the container, even despite the shape of the container. (note that this is not in chronological order but merely a description of how the substances will be arranged once they have been given enough time)

My reasoning is that since the most dense substance ( call this "L1" for liquid 1) will have the largest and strongest gravitational pull. All of the particles of this liquid have a stronger attraction than any other two particles to eachother. The liquid with the second highest density ("L2") will be first attracted to L1, meaning it will move as close to it as possible, closer than any other particle will. Since the third highest attraction after L1=>itself and L2=>L1 is L2=>itself, all of the L2 particles will form a layer together evenly distribute surrounding L1. Other liquids in the container will successively mimic the behaviour of the first two liquids, forming more layers.

The reason I came to the conclusion the the particles would form a sphere is that in our example on earth the partitions between the substances were perpendicular to the force of gravity. I bet that if you made a container that was as wide as the earth and set it down or hung it by string from the moon whatever, the partition would be curved in a way that if you took the perpendicular to a tangent of this curve and drew it from the point of intersection with the curve, it would point straight to the center of the earth and the length each of these tangent's perdicular from the curve to the earth will be equal(i.e. parallel to the force of gravity.) Thus the ideal arrangement of the liquids in our container would be a sphere with the source of the strongest gravity, which is L1, at its center. Now the next layer can be formed and the properties of the partition in the example on earth is identical to the ones in our container which is unaffected by outside gravitation.

I am no physics major, in fact I dropped all sciences in grade 11, so I have no idea if this is the case or not. For all I know the liquids don't move at all when they are not affected by the gravity. If this is the case it supports my thoughts, so please someone confirm this.
