Slightly Below Three Attoseconds

Dreaming of the shift between
Isotopes of hydrogen,
A delay between lighter

And heavier nuclei,
The slow thoughts uncurl like smoke
In a thawing atmosphere.

A billionth of a billionth
Of a second, well, let’s see.
Half a second is a blink.

There are eight billion, roughly,
Human bodies blinking now.
So sixteen billion moments

Could be slicing each second,
Sequentially. Not enough.
