Astronomers are on the Hunt for Dyson Spheres - Lemmy.World
Let’s say we detect one in some other galaxy. What then? And how do you reach out to them?
We don’t because we can’t. We will just observe the thing for science and stuff.
IF (and that’s a big if) it would lead to clues how to build one. And we could direct communications precisely at it and hope for something to come back.
