Cosmology is the study of the origin, evolution, and structure of the universe.
Let's say you have a big ball of dough and you start to roll it out. As you roll it out, the dough gets thinner and thinner. The universe is like that dough. It started out very small and dense, and it has been expanding ever since.
Cosmology is the study of the universe.
Noun: cosmology.
Adjective: cosmological.
