FIELD: future space engineering; interstellar flights.
SUBSTANCE: proposed method is based on use of reactive thrust of spacecraft rocket engines in their maneuvering in gravity field of black hole. Kerr (rotating) black hole, i.e. its ergosphere may be selected for the purpose. Several separate spacecraft are directed in succession to gravity field of black hole ensuring stable exchange of information among them (for example, by radio or light channel). Provision is made for acceleration of spacecraft to relativistic speeds and obtaining information on effect of such speeds and accelerations on physical processes, equipment and living beings (at safe flying out of sphere of influence of black hole), as well as verification of theories of black holes.
EFFECT: enhanced efficiency.
