Pinpoint

How do I reconcile you with supernova
in nuclear reaction a trillion miles away?
How do I draw the line of mass extinction
fossilized in rock a million years ago?

The way those germs test your immunity,
the microscopic made tangible, visible -
your infinitesimal spec undermines the galaxy,
substantiates a little world of purpose.

What imperative guides my steering hand?
hard-coded altruism or absolute morality?
Stars come and go. The universe expands.
Our moment toys with time in eternity.
