The Z-Files & Other Wonderous Tales — an archive of short speculative fiction

In 2041, a selenographic photometry specialist named Dr. Amara Veyr discovered that the Moon reflects 0.00031% more light than it receives.

The discrepancy appeared only during the final 11 minutes before total lunar eclipse. It was too small for ordinary observatories, but Veyr’s cryogenic photon array recorded it across 46 consecutive nights, using calibrated lasers bounced from six points on the lunar surface.

Every calculation agreed. During that narrow interval, the Moon produced light without an identifiable source.

In 2041, a telecommunications engineer named Dao Xu noticed something wrong with the global internet backbone. Not a bug. Not latency. Something extra.

Mixed into the petabytes of daily traffic, hidden beneath layers of protocol noise, was a signal. Constant. Unbroken. Present on every cable, every satellite link, every fiber optic line on Earth. It had been there since at least 1994, possibly earlier. No one had noticed because it looked like noise. It was shaped to look like noise. Perfectly camouflaged.

When isolated and decoded, the signal was not data. It was not communication.

In 2036, a linguist named Dr. Tomás Herrera was cataloging endangered languages in the Peruvian Amazon when he encountered something that shouldn’t exist: a language with no words.

The Oravá people, seventeen remaining members, uncontacted until 2034, communicated fluently, constantly, unmistakably. They argued. They told jokes (they laughed). They made decisions collectively. They sang their children to sleep.

But they produced no phonemes. No clicks, no tones, no whistles, no gestures, no sign. Their vocal cords were healthy. Their hearing was perfect. They simply… didn’t use sound. Or movement. Or any observable medium.

In 2033, a bored data scientist named Petra Voss ran what she thought was a joke experiment. She weighed objects, precise to the nanogram, before and after naming them.

A rock on a scale: 142.0000000 grams. She looked at it, decided its name was “Harold,” and spoke it aloud.

142.0000003 grams.

In 2031, a rogue acoustics researcher named Dr. Yuna Khalis discovered that every human being emits a unique sub-audible frequency, a tone so low it falls below 0.001 Hz, inaudible to any ear, but measurable with sufficiently sensitive equipment. She called it a person’s “soul note.”

The crazy part? When she mapped 10,000 people’s soul notes onto a musical scale, they formed a coherent melody. Not noise. Not randomness. A composition, one that appeared to be incomplete, as if humanity itself were a symphony still being written, and each new person born adds the next note.

She ran the melody through a predictive algorithm to extrapolate what the “next notes” should be, and the names it generated matched birth records from the following year with 94.6% accuracy.

In 2027, a distributed neuroscience lab in Kyoto accidentally left a prototype EEG mesh running on 2,400 sleeping volunteers simultaneously. The mesh wasn’t just recording brain activity, it was cross-correlating it in real time. What they found broke three researchers and got the project permanently defunded.

During deep REM sleep, between 3:00 and 3:44 AM local time, roughly 7% of all sleepers were navigating the same place.

Not similar imagery. Not archetypes. The same topologically consistent space, a vast, sunless city with non-Euclidean architecture that nonetheless obeyed its own internal geometry perfectly. Subjects who had never met drew maps that overlapped. Street names, in a language no linguist could identify, matched between strangers on different continents.

1. Carry the morning float downstairs before Mr. Pritch unlocks the street doors. The counting room will be cold. Light the small stove, but leave the upper window open until the blue smell of gas has gone.

2. Test each carrier with a penny and a blank sales slip. Six should return at once. The seventh may take longer. Do not strike the pipe. It dislikes being hurried.

3. The carriers are brass, lined with green felt. Keep the rims greased with tallow. If one returns warm, set it beside the stove until it cools. If it returns smelling of wet wool, open it at once, even if no bell has sounded.

I am replacing the hall grille when Clara asks why I have put the screws in backward.

They are not backward. Their heads face the passage so I can remove them quickly, should the need arise. A screwdriver is kept in the blue bowl with the door keys. Clara knows this, though she pretends not to. Children prefer a mystery when the explanation asks something of them.

The grille belongs to the air return. It is larger than the heating vents and set low in the wall, where it gathers crumbs, cat hair, and the grey felt that comes off old coats. Margaret used to clean it with a pastry brush. For an hour afterward, the rooms smelled faintly of pear soap.

I clear the leaves from Bracken Row every Thursday, and the fox comes behind me.

She is a small vixen, dark along the spine, with one white forepaw. She waits while I lift the wet plane leaves from each drain, then lowers her muzzle to the iron and listens. Cars pass within a yard of her. She pays them no attention.

People here have always said the foxes count us.
