By 25 century, Human kind has spread away from our solar system and the milky way by starting to dominate intergalactic FTL travels, yet, earth is still the prime home for humanity, due to our short time traveling through galaxies, most of the travels are "no return expeditions", without even being able to communicate back to earth when very far. Also no other kind of intelligent life has been found.
In one of those expeditions, half the way to their destiny, in one of the many stops between FTL jumps (which last a few seconds and use to be near a planet or a star), a passenger at work looks through the window to see below on the planet, city lights!
The sad part of the story, is that in a few seconds that image will disappear, with no option of returning back, and the secret she just discovered will probably never be known by human kind, just a memory in her head doomed to vanish in the dark like her short human life.
also don't forget to leave a comment, this specific piece took a hell of time (and work) to be properly finished.
