Matter-Antimatter Twins Poem by Tor Magnor Solvang

A neutron's twin, but not the same,
An antineutron, a curious name.
Same weight it carries, light and free,
No charge it feels, for all to see.

But deep inside, a flip is made,
A spinning force, a different grade.
A counting game, a number spun,
One way for here, the other's run.

If normal parts are close they stray,
They vanish in a bright display.
Their stuff turns light, a fiery gleam,
Gone in an instant, like a dream.

From tiny bits, a mirror made,
A world reversed, unafraid.
When scientists, with careful eye,
Found this strange twin, beneath the sky.
