Science Fiction

Each evening, shortly after sunset,

darkness covers the land.

Having mystified thinkers for millennia,

the mechanism for this occurrence

has now been identified: migration.

Darkness, it has been found, is composed

of an almost infinite number of particles,

which roost and reproduce up north

where they have fewer natural enemies:

Forest fires, lampposts, lasers, blazing sunlight,

torches, candles, lighthouses, limelight, and electricity

are relatively rare in the polar regions.
