The computer’s analysis scrolled up the screen: Unknown. Trajectory suggests origin point outside the Local Group. AGE OF SIGNAL: Approx. 4.2 billion years. DECODED CONTENT: Single repeated phoneme. Phonetic approximation: “WAAA.” TRANSLATION: None. No known linguistic root. EMOTIONAL SIGNATURE: Grief. Abandonment. Longing. Aris played it again. And again. By the third repetition, he noticed the anomaly the AI had buried in the metadata: the waveform was decaying . Each iteration was 0.003% quieter than the last. The signal wasn’t repeating. It was fading. A new file
