Is it possible for an object's center (eg an a perfect sphere) to allign perfectly with centers of two other objects in reality? Theoretically it seems possible if you place identical balls on a perfect plane and roll one ball past the line created by two objects, but i dont think such plane is possible..

Concentric circles or spheres?

spheres.. but anything really with a defined center

Are you just asking if it's possible to get the exact centers of 3 separate objects to line up, or whether it's possible to have three separate objects (presumably one within another) to have the same center?

Concentric anything works actually.

I really didn't get the "identical balls and roll one ball past the line created by two objects" thing at all, I'm pretty sure that doesn't work.

Correct me if I'm wrong

So your saying if two identical spherical balls possessed an axis on a flat surface, could someone theoretically roll another identical sphere that would fall on the axis.

Well presumably yes, but the chances would be extremely low for such an event to occur. Like hitting a bull's-eye from gigametre away.

it is possible if such objects are intangible
