What Happens to Their Atoms

A short, contemplative companion to the main grief bundle — a Feynman-inspired reflection on what physics says cannot be lost.

When the loved one's body is gone, the atoms that were them are not gone. They have been redistributed into the cycles of the biosphere, and some of them are now, measurably, in your own body. This is not metaphor. It is what the first law of thermodynamics says, and it has been true for over two centuries.

This 10-chapter book takes that fact seriously. It walks through where the atoms of a human body come from (stardust, literally), where they go after burial or cremation, what conservation of matter actually says, and the specific math of how many of the loved one's atoms are now in the survivor's body through breath, food, water, and shared environment.
