These elements occupy corresponding elements of timeless spaces.

An object located in an element of an instantaneous space will also be said to be located at that moment in the timeless element of the timeless space which is occupied by that instantaneous element.
It is not every object which can be located in a moment.

An object which can be located in every moment of some duration will be called a 'uniform' object throughout that duration.

Ordinary physical objects appear to us to be uniform objects, and we habitually assume that scientific objects such as electrons are uniform.

But some sense-objects certainly are not uniform.
