On the TV show, every star seems to have at least one planet technologically equal to c2000 AD Earth. If this were reality, would we know it?
I have heard it said that our TV shows fade into invisibility within a couple light years. Our DEW radar can be picked up by Arecibo to something like 100 light years, but only if we are looking at that point, on that frequency, at that instant. And even then we would just get a WOW! signal or a TYC 1220-91-1.
So have we ruled out a Startrekverse? Not that I believe it, but have we looked at the universe deeply enough to PROVE it false?
