*As I recall, LC was referring to radio waves emanating from radio
broadcasts. In any event, there some obvious possibilities why we have not
made EM contact with extraterrestrials. Maybe the Milky Way is too young
for a galactic civilization to come into existence, and/or, advanced
civilizations might decide NOT to broadcast due to the possible existence
of predator species. As for your definitive negative evaluation of Roswell
having been an alien contact, I fail to see any basis for your conclusion
other than bias. AG *
