astroengineering
The construction of very large artificial objects in space by technologically advanced beings. Searching for the radiation signatures of such objects, it has been suggested, represents an important alternative strategy in SETI. Among those to put forward specific suggestions in this regard are Freeman Dyson, with his remarkable Dyson spheres, and Nikolai Kardashev, with his classification scheme for advanced technological civilizations.
