Quantum Effect: the Double Slit Door

When she was ten years old, Lin Che's father demonstrated the double-slit experiment on a thunderstorm night. Interference stripes should have appeared on the screen, but deep within the stripes, his mother, who had been dead for three years, emerged. After the white light passed, his father disappeared, leaving only a few burnt words on the experimental screen: The third slit is not for us. Twenty years later, Lin Che saw her mother again in an abandoned surveillance video. People in photos will move, missing people will return from old films, non-existent old streets reappear at night, and disappeared trains are bound for a city that is not on the map. He finally discovered that the double-slit experiment revealed not the secrets of microscopic particles, but the cracks in reality itself. Schrödinger's City, Photoelectric Ghost, Macroscopic Tunneling, Entangled Civilization, Observer Project... All exceptions point to the same place: The third seam. Hidden there are all the people, cities, history and civilizations that have not been selected by reality. And outside the door, something is observing the earth. My father once said: "The real danger is not what you see, but what sees us through your eyes." Now, observations have begun. Once human civilization is completely determined, all futures will collapse into a single ending. That's not destruction. That is more terrible than destruction—eternal certainty.
