At left, a Dyson Sphere of an advanced civilization (Kardashev Scale, Level 2) capturing the energy of a whole star to drive their civilization. At right, the space station from the movie 2001 Space Odyssey which effectively depicts technology of an emerging space-faring civilization (Level 1). Do thousands of years separate the technology levels or just a few hundred years? Does advanced intelligence mean ever greater demand for energy? Image Credits: MGM, CP
