There Are Stars Behind the Door

Over the past 300 million years, all civilizations in the Milky Way that have reached their end have left behind the same relics: a book. A blank page. And one sentence: "We prove it. But we don't write it." The young mathematician Shen Zhiyuan completed the proof, only to find that his father had already reached the same position twenty years ago. Facing 300 million years of silence, he must answer a question that is more difficult than the universe's answer: If knowing the truth would change a civilization, then who has the right to decide whether the truth should be revealed? This is a story about the universe, civilization and choice. For those looking for answers. About those who choose silence. It's also about how one eventually learns: True freedom is not having answers. But in the face of the answer, you still retain the right to choose. Behind the door, there are stars.
