Re: What about 0 gravity at the bottom of the well?
false.
there is zero net gravitational attraction in any one direction, but there is still massive gravity affecting the universe fabric.

Re: What about 0 gravity at the bottom of the well?
stretched between, compressed at mass locii ... like topology of a foam mattress with bowling balls on it, and the closer to the "massive" objects the more drawn to them you are by the curvature
a rolling marble.
I thought Barycenter was where chuck was on stage ....

Re: What about 0 gravity at the bottom of the well?
funny, I think of it as being more compressed, like the foam under the ball. I guess it is from visualizing the gravity lines like a topological map and seeing them closer together at the denser objects and so the are compressed in one view. of course if you look from the "side" they would be seperated out.
it's a matter of perspective.

Re: The original metaphhore
true.
but. there is still a problem with gravity not matching observation to theory without throwing in some epicycles of dark matter and epicycle on epicycle of dark energy ...
something is not ... quite ... right yet.

Re: What about 0 gravity at the bottom of the well?
would you fall to the center? or would you be able to stand on the inisde? you would have to integrate all the dM/dd2 increments but I suspect that you would get a net force holding you to the underside, and you might find the ring analogy holds ... in 3D.
enjoy.

Re: The Milky way IS in the "center"
it is in the table code: you can see where it is from the qs box.

this is the table without the caption or border padding or the TR callout for the first line:

Re: The Milky way IS in the "center"
Everything is the center. There is no way to distinguish one part from any other in terms of centrality, therefore they are all equally at the center.
You say FG = GmM/d2 is the force of gravity between two objects ...
But when you sum up the known mass of a galaxy and compare the way it rotates with the sum of these forces we end up with a problem: the outer arms are spinning too fast.
This means EITHER that not all the mass is known (and there is "dark matter" (and when that doesn't account for an even larger scale accounting on the universe level, "dark energy")) ...
OR the equation of gravity is not ... quite ... right ... yet.
There is evidence that we do not fully understand gravity, from the problems with a Grand Unifying Theorum (GUT) to the lack of observation of any form of graviton, what we really know is very very little.
Maybe at the subatomic level the universe is wrapped up on itself as some of the string theory ideas lead, and what we are seeing is not an absence of matter, but an absence of distance in another dimension.
Enjoy.
ps -- nice cyan color sylas, it helps to show where the editing takes place.
