Interstellar Archaeology on the Galactic Scale

Interstellar Archaeology on the Galactic Scale: "What would happen if a true galaxy-spanning civilization went to work on the kind of astroengineering it would be capable of? We call this a Kardashev Type III civilization, one that could exploit the power resources of an entire galaxy, and my assumption has always been that such a culture would be blindingly obvious, its projects so vast that our astronomers would be able to detect them by noting anomalies that could hardly be natural occurences. Imagine, for example, a galactic culture that encloses each individual star in a Dyson sphere."
