There are still ways to make the hypothesis work: a megastructure swarm might radiate its gathered energy away as
radio or laser
signals instead of heat; it might not form a spherical swarm but a ring precisely aligned with our line of sight; it might use technology beyond our understanding of physics that
emits no heat at all.
Such
radio traffic could be readily apparent On the earth, for example, a new radar system employed with the telescope at the Arecibo Observatory for planetary studies
