(13,409 posts)But if you're suggesting that radio and microwaves are the most efficient way of communicating long distances, that's simply not true. Lasers can communicate far more quickly and efficiently than radio and microwaves. However, it's most likely that any advanced civilization would be communicating over some form of broad or multiband. That's most likely why we, while looking for nothing beyond single band communication, encounter absolutely nothing intelligible. And once again, even if we WERE looking for radio waves, what makes you think we'd be likely to find them given what an insanely small portion of the sky we're capable of monitoring?
And you seem to be entirely contradicting yourself with your second statement. You seem to admit that those who are most resistant to the thought of intelligent life not being unique to our earth are those ones most likely to destroy it.
