My husband says dark matter is a reality
not just some theory invented by adolescent computers
he can prove it exists and is everywhere

forming invisible haloes around everything
and somehow because of gravity
holding everything loosely together

the way a child wants to escape its parents
and doesn’t want to—what’s that—
we don’t know what it is but we know it is real

the way our mothers and fathers fondly
angrily followed fixed orbits around
each other like mice on a track

the way every human and every atom
rushes through space wrapped in its invisible
halo, this big shadow—that’s dark dark matter

sweetheart, while the galaxies
in the wealth of their ferocious protective bubbles
stare at each other

unable to cease
proudly
receding

In nature, molecules are chiral—they turn in one direction or the other. Naturally then, someone wondered: might sugar, built to mirror itself, be sweet, but pass through the body unnoticed? A dieters’ gold mine. I don’t know why the experiment failed, or how. I think of the loneliness of that man-made substance, like a ghost in a ‘50s movie you could pass your hand through, or some suitor always rejected despite the sparkle of his cubic zirconia ring. Yet this sugar is real, and somewhere exists. It looks for a left-handed tongue.
