 Supersubstantivalism is often glossed as the view that each material object is identical to the spacetime region at which the object is exactly  located.[7]  If supersubstantivalism is not just true but necessary, then it is impossible for disjoint material objects to be exactly located at overlapping regions. After all, if material object x is exactly located at region r1 and material object y is exactly located at r2, and r1 and r2 overlap, then, given supersubstantivalism, x=r1 and y=r2, and hence x and y overlap as well.
