Important point From the previous messages:

Imagine the surface of the Earth. Where is the center of the surface (no digging allowed). There IS none. That's not 100% accurate.

It sure is!

In our search for the center of the earth we're lucky enough to have a very powerful clue, i.e., gravity. A plumb bob points directly at the center of the earth.

And any where you stand on the surface it will point straight down to that point on the surface. Assuming a perfect sphere (force due to gravity does not change with position on the surface). It does infact points to the center of volume(approx.), but not the center of the surface like the question above posed.

Of course, your comment is based on a 2-Dimensional creature, and gravity is working on that third dimension, and I'm no physicist, but couldn there not be some equally cool extra-dimensional force that would point us in the direction of the center of our 4 dimensional universe?

If there is a "cool extra-dimentional force" it already is pointing us to a "supposed center" ... It is all a matter of being able to "visualize" in a higher dimentionality. Take the original example from above. Imagine that we did not know the earth was a sphere(approximately). To us the surface of the earth would appear to wrap around on itself and have no apparent center. if you walked in a straight line(no turns) on the surface you eventually would end up back at the same spot. Hence the added dimentionality of viewing the problem in 3-D vs. 2-D gives us that apparent "cool extra-dimentional force" .

Just my 2 pennies which is even less noew that the dollar is down.
