It could be that a great many of highly advanced civilizations will have utilized psychic communication, which may only detectable by psychic means,
which means they will have devised some form of protection, defense or encryption... Although there would still be a great number of
species/civilizations that either have not yet mastered psychic communication or long distance psychic communication, or they can do it but still use
other means for most communications or long distance communications.
We have an ever expanding bubble around earth moving at, I guess the speed of light...that contains all our radio and TV communications. I guess the
first visual signal was Hitler giving a speech. So the first thing the others will see of us humans, is Hitler. They can hear other stuff in radio
signals before TV was broadcast, so it won't be the first information they get from us at least.
But anyway, that bubble, or I guess it's more like a solid sphere, packed full of our communications, until we stop broadcasting, then it will be a
bubble with a shell. I wonder how thick that shell will be? Right now it's about what? 75-85 light years thick? And when that shell hits another
civilization with radio tech, they will get a 85+ year "drama" about the human race. I'd never get any sleep wanting to stay caught up in the
activities of these humans. They would have a show just for condensing and playing the most interesting parts. I'd be on the edge of my seat during
ww2... and then to have our scientists tell us this all happened a few thousand earth years ago?
Maybe we are about to run into another planets radio shell. Would such a shell be detectable before it hits you? I just want to examine another
planets broadcast history!
