A satirical-philosophical science fiction novel by Stanisław Lem devoted to the adventures of the fictional space hero Ijon Tichy.
In the novel, Ijon Tichy travels to the distant planet Encia to study the civilization living there. The title is connected with verifying information about this planet received by computer-generated generation (prediction by modeling) on Earth. Lem developed Encia’s history in enough detail—from primitive times to the present day (meaning the time period of the novel)—and also showed the social independence of the Encian society.
