“The Fermi paradox, named after Italian-American physicist Enrico Fermi, is the apparent contradiction between the lack of evidence for extraterrestrial civilizations and various high estimates for their probability” {“Fermi paradox,” in Wikipedia). The objection is to be represented as a not less paradoxical, “quantum-mechanical explanation” for it. The explanation relies on the non-invariance of physical laws after the space travel if quantum mechanics is valid.

A necessary condition for any space travel is the constancy of all physical laws during it. It is not satisfied in the “ideological universe” in general. Thus, “they are not here” because they cannot come here in the “ideological universe”.. The space travels in the “ideological universe” are possible only at a distance short enough for the physical laws to be constant approximately. The formulation of Fermi’s paradox does not admit for the physical laws not to be constant during the travel, which is the formal and logica reason for the contradiction.
