Sorrow Has a Half-Life

Sorrow has a half-life

decaying, one atom at a time

but never fully gone,

proving Zeno right.

Joy, too, once all-consuming,

degrades with the days

until the memory is sweeter

than the moment

that gave it life.

They say the universe, 

though now expanding, 

will one day cease 

and then contract again

collapsing in upon itself

like the memory of joy

and of pain

until, undifferentiated,

all becomes one.
