The measurement or mathematical description of the universe and its structure; a system of measuring cosmic distances and proportions.
From Greek kosmos (universe) + -metria (measurement, from metron meaning 'measure'). This technical term combines the ancient Greek desire to measure and understand the physical dimensions of creation itself.
Ancient geometers like Eratosthenes used cosmometry to actually measure the Earth's circumference 2,000 years ago using just shadows and mathematics—proving you don't need modern technology to understand cosmic scale if you think cleverly.
