>If you want to go off on flights of fancy, then anything is possible, but there's no way to say anything useful about it. I would guess, though I could be completely wrong, that a civilization that both had access to far more advanced 'sci-fi' level technology and wanted to broadcast it's existence would also have an understanding of the technology other civilizations would have access to and would choose to broadcast using numerous 'ancient' technologies that more privatize civilizations could pick up on. When we sent probes out into space to broadcast ourselves, we realized we couldn't just write a message in English and as such tried to send numerous different ways of conveying information, some linguistic and some not.
