You are all stardust.

Every atom in your body came from a star that exploded.

你身体里的每一个原子都来自一颗爆炸了的恒星

And, the atoms in your left hand probably came from a different star than your right hand.

你左手的原子与右手的原子也许来自不同的恒星

It really is the most poetic thing I know about physics:

这实在是我所知道的物理学中最富诗意的东西：

You are all stardust.

你的一切都是星尘

—Lawrence M. Krauss
