This is true for every physical object though. You cannot tell me with perfect certainty the width of a ball of tungsten, because the edges aren’t actually rigidly defined. In fact: it doesn’t really have an “edge” the way you might think of it geometrically. Just a boundary across which forces start interacting with each other.
