The concept of “location” arises in the context of entities which are at rest

“Between 4:00 and 4:05 p.m., the car was moving through New York City.” One can
narrow down the time period and, correspondingly, the region; but one cannot
narrow down the time to nothing in the contradictory attempt to locate the
moving car at a single, fixed position. If it is moving, it is not at a fixed
