SEASON 3: The Garden of Stones

  Episode 7: First Contact (The Recording)

  The silence in our white room was visceral. We stood paralyzed around the holographic projector as Argus began to unpack the first data packets from the Precursor probe.

  At first, there was no image—only raw arrays of telemetry. Graphs. Spectrograms.

  "Atmosphere," Argus’s voice was devoid of emotion, but the sheer speed at which the data flooded the display betrayed his computational intensity. "Anomalously high levels of free oxygen. Ozone. But the most intriguing data lies in the trace impurities."

  A trembling line of spectral analysis hung in the air.

  "Look here," Kenji pointed to the peaks in the spectrum captured as the probe scanned the planet’s terminator.

  The line on the night side didn't drop to zero.

  "Photoluminescence?" Ares suggested immediately, instinctively looking for a catch. "Luminescent plankton? Radioactive minerals? Geothermal activity?"

  "The range is too narrow," Alex shook his head, his eyes burning with a feverish light. "Look at the bandwidth. This isn't the thermal radiation of lava. It’s not the chemistry of biology. This is monochromatic light. The spectrum of LEDs or lasers."

  Argus performed a final scrub of the data, filtering out the background noise. Then, he projected what the probe’s telescope had actually "seen."

  It was a blurred smudge, only a few pixels wide. But a mathematical analysis of the brightness revealed a distinct pattern impossible for nature to replicate. Spectrally pure, brilliant blue light.

  "It’s artificial illumination," I whispered.

  If you stumble upon this narrative on Amazon, it's taken without the author's consent. Report it.

  In that moment, the boundaries of the white room vanished. We forgot that we were digital ghosts trapped in a flying shard of crystal. We were shouting. We were laughing. Kenji, usually so reserved and cold, was punching the air in triumph. Ares wore his predatory grin, but for once, it was entirely free of cynicism.

  We were not alone. The universe was not dead. We had found them.

  We didn't sleep after that. There was no point in lowering our clock speeds. We hungrily "caught up" with the history of the Precursor’s flyby, which had occurred four years ago in our local time.

  The probe hadn't slowed down. It had hurtled through the Eridani system at 0.8c. It had only hours for a close approach and mere minutes to deliver its message.

  Argus showed us a reconstruction of that moment.

  As the Precursor streaked past the planet, it began to pulse a laser—a universal greeting code: a sequence of prime numbers, the structure of the periodic table. It flashed into their violet sky like a swift, impossible comet.

  The odds that they would notice the signal in those few seconds were infinitesimal. The odds that they would respond in time were even smaller.

  But they did.

  Data from the probe’s aft-view cameras, already receding into the dark, captured a flare. The planet had answered. They used their high-altitude clouds as a gargantuan projection screen. Massive lasers fired from the surface, illuminating the stratosphere from within. And upon the clouds, a response materialized.

  It was the same sequence of prime numbers.

  "They understood," Alex whispered. "They instantly realized it was a signal, and they answered in the same language."

  Following the numbers, symbols began to appear on the clouds. Simple, angular glyphs composed of square elements.

  "An alphabet," Argus commented, analyzing the stream. "Twelve base symbols. Each constructed within a two-by-two matrix. It’s digital writing. An optical code."

  We watched those blurred symbols, fading into the distance, with a sense of profound reverence. These weren't radio waves. This was pure light. Their entire civilization, judging by the spectrum and the reaction speed, was built on optics.

  The remaining years of our flight became a schoolhouse. We analyzed these crumbs of information, attempting to reconstruct their model of thought. We finally understood why the radio had been silent: for beings who live at the speed of light and communicate via lasers, radio waves were too slow, too unreliable, and too "dirty."

  We called them the Photoneans.

  We weren't flying to them as conquerors, or even as explorers. We were flying as students who had been given their first homework assignment—and who were terrified of failing the exam when we finally met.
