"Apeiron: The Logbook of the Pilgrim-3 (the catastrophe of the 'Deep Breakthrough' mission)", a science fiction short story

The story "Apeiron: The Logbook of the Pilgrim-3" is a work of fiction that illustrates the theoretical concepts of the IDM (Infinite-Dimensional Multiverse Model), 7FM (Seven Forms of Matter), and the physicalist interpretation of the Apeiron. Written in the genre of hard science fiction and presented as a ship's logbook, it is not a scientific paper but employs the "found document" device to create a sense of authenticity. Plot: the expedition ship "Pilgrim-3," during a mission along a chain of universes, exits the multiverse and enters the Apeiron — a region where familiar space and time are absent. The crew records unusual phenomena: a pulsating haze, statistical clusters that change shape, and the "Blind Witness" cylinder which, instead of time, traces spirals. Gradually they discover that the Apeiron is not empty — it possesses structure, recodes matter at the level of interatomic bonds (the apeironite effect), and affects the crew's neurochemistry, causing reduced reactivity. The xenobiologist hypothesises the existence of "apeironic informational structures" — analogues of organised systems. The crew decides to synchronise the generator with a pulsar to perform a coherent breakthrough and return. The story raises questions about the boundaries of knowledge, the nature of reality, the impact of an alien environment on the observer, and the ethical limits of intrusion into the unknown. All phenomena described are speculative extrapolations of hypotheses, not statements of scientific fact. The text is addressed both to science fiction enthusiasts and to researchers familiar with the author's work, and concludes with an invitation to dialogue.
