Dragging the discussion back in the direction of the F of R, one has to wonder who, or what, occupies my F of R? The simple answer might seem to be "I do", but as pointed out above, parts of me move relative to other parts, and there can be no movement within a F of R. Even my brain cannot occupy my F of R, because there is activity in there (I'm sticking to that, in spite of any contrary evidence). Every synapse has its own activity. Following this line of thought, it begins to look as though no physical entity can claim to occupy a F of R. Increasingly, the F of R looks like the "present", the closer you try to look at it, the more elusive it becomes.

There never was nothing.
