Plural of cosmology; different theories or systems that explain how the universe is structured and how it came into being.
From Greek kosmos (universe, order) + -logia (study of). The Greek root originally meant 'order' or 'arrangement,' reflecting ancient philosophy's view that the universe followed orderly principles rather than being chaotic.
Throughout history, different cultures developed completely different cosmologies—some imagined the universe on the back of a turtle, others as a rotating sphere—yet modern physics has revealed that each culture was asking the exact same fundamental questions about existence that we still puzzle over today.
