“There is only a perspectival seeing, only a perspectival ‘knowing’; and the more affects we allow to speak about one thing, the more eyes, different eyes, we can use to observe one thing, the more complete will our ‘concept’ of this thing, our ‘objectivity,’ be.” — Nietzsche:On the Genealogy of Morals III
It's a target. Objectivity does not appear in nature in a stable form. Nothing is fixed and certain. Some things just appear that way from our point of view.
My own addendum: the atoms are stories, too.
