The life and work of all people on Earth are controlled by the Planning Machine. Those who do not live up to her hopes are sent for recycling, to the organ-bank. If someone’s activity is recognized as anti-plan, then a special iron collar is placed around that person’s neck and reclassified as a dangerous person (oops). It is impossible to remove the metal ring yourself. At any time, the machine can send a coded radio signal to it and the ring will explode. Only Ron Donderevo was able to get rid of the ring and escape from the Gliding Machine into the Reefs of Space. There he founded a colony of free people. The reefs of the Cosmos are celestial bodies far beyond the orbit of Pluto. Reefs are inhabited by special life forms: fusorites, pyropods, spatialites and others. These animals move through space on a special non-reactive thrust, not based on opposition, which by its existence refutes Newton's third law.
