Everything is Illuminated

One swallow skims the surface swooping low,
and his reflection rises to the bait.
His likeness and his image, head-to-toe;
Narcissus and his true-love strain to mate.
Another world, the twin to this, our own,
just one of many painted by Monet.
What strange Intelligence might call it "home"
Is more than 4-D mortal man can say.
Two worlds encounter at the mirror-plane
Or so 'twould seem, exchanging left for right.
It took a Snell to lucidly explain
the symmetry of such reflected light.
String theorists insist on seven more
dimensions, but can't make clear what they're for.

C-symmetry sets anti-matter's bounds
it must behave like ordinary stuff
yet here on Earth it's been so rarely found
that characterization has been tough
bad novelists feel free to speculate
about a cosmos where all seems reversed
but which is "positive" and which its mate
is just a matter of which got named first
except neutrinos there are all "spin right"
while here they spin like the left-handed do
no measurement of length or width or height
could reassure that you're the real you
all other tests, that world would freely pass
although you're stranded through the Looking Glass
