The story “Kyrie” is a requiem for an astronaut falling into a “black hole” (from the point of view of his friend, who remains at a sufficient distance from it, the astronaut who died long ago in the bowels of the star is, as it were, still alive and even giving distress signals! For friends with the basics of the theory of relativity, such relativity of time will not seem so incredible...)© V. Gakov
