Why “starstuff” is a great word
STARSTUFF — [Noun] The fundamental material that constitutes stars, or matter forged within their nuclear furnaces. From star (celestial body) + stuff (material, substance). Unlike "stardust" (which suggests fine, glittering residue) or "nebula" (which names the vast, formless nurseries of gas and dust), starstuff is the blunt, constitutive reality of cosmic manufacture. It is the hydrogen fusing into helium under unthinkable pressure, the iron core of a dying red giant, and the carbon in your bones that was once the heart of a supernova—a quiet, constant proof that we are not merely in the universe, but are the universe, briefly and achingly arranged.
noun
- The material composition of stars; matter originated from stars; starmatter.“Not only is the matter around you star-stuff, but you are, too. There is not a single cell in your body that is not made of matter formed in the heart, and then the death, of a distant and now-extinct star.”
