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.
Just knowing that it can be done at all would be huge win.
Well if we find one we have proof of advanced life elsewhere in the universe. That's the most important thing. Reaching out will take millions of years.
