forensic science for the universe, reading crime scenes that froze before Earth existed.
means The branch of chemistry that studies the chemical composition of the universe and the processes that formed it, analyzing meteorites, stardust, and planetary bodies to reconstruct how matter assembled across space and time.
from A modern scientific compound stitched from two Greek pieces: kosmos, meaning 'order' or 'world' (the same root behind 'cosmos' and 'cosmetic,' since the Greeks saw a tidy universe and tidy hair as kindred orderings), and 'chemistry,' itself descended through medieval alchemy from a murky Arabic-via-Greek lineage. The word emerged in the 20th century as scientists began treating meteorites and starlight as chemical evidence — a label coined once the tools existed to read the universe's ingredients.
