A civilization reaching level I status according to the Kardashev scale still does not have the capacity to expand at the level of its solar system or its galaxy system. This is not the case of a type II civilization that has managed to emerge to exploit all the energy of its sun ornsolar star. The Death Star for example is a fictional space station within the universe of the film Star Wars (3), that could be constructed by a civilization in the scale of type II of Kardashev to emulate the sphere of Dyson, a hypothetical megastructure proposed in 1960 by physicist Freeman Dyson, in an article in the journal Science called “Search for artificial stellar sources of infra-red radiation.”
The sphere of Dyson is basically a spherical shell of astronomical magnitude, with a radius equivalent to that of a planetary orbit around a star, which would allow an advanced civilization to take full advantage of the luminous and thermal energy of the star.(4) Type II civilization would have the power to control large-scale processes such as deflecting comets, asteroids or diverting glacial processes on a planetary scale or even the global warming process in which we are immersed.
