出自一位理論物理學家的浪漫詩句：
你身體里的每一個原子都來自一顆爆炸了的恒星，
你左手的原子與右手的原子也許來自不同的恒星。
這實在是我所知道的物理學中最富詩意的東西：
你的一切都是星塵。
Every atom in your body came from a star that exploded.
And, the atoms in your left hand probably came from a different star than your right hand.
It really is the most poetic thing I know about physics:
You are all stardust.
—Lawrence M. Krauss
