What is the setting in the poem, A World Made of Atoms?

The poem does not have a specific literal setting. This suits its absence of characters and plot: this is not a poem that is about events, or that is intended to mimic reality. Instead, it is a poem that takes a philosophical and abstract approach to setting. The poem does not depict the world's physical reality, but rather imagines it through a series of metaphors that allow the reader to understand how the constant motion of atoms created it.
