[1] Hence, subject areas cover an exploration and investigation of nature and substances that exist in the world and the universe, from atomic to cosmological scales.

This encompasses defining and describing observations, interactions, and forces which occur in nature and, hence, in substances.

More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.
