If large lifeforms are not nearby, how would we distinguish between their Dyson spheres and the (observed) prevalence of dark-matter?
Thermal radiation...?
If I were building a dyson sphere, I’d want to collimate all the radiation toward a single direction, perhaps gating it periodically. Make it look like a pulsar.
We’re surrounded by stars in all directions, and that would be far from free.
