Well, that would explain the silence.
As David Papineau notes in last Sunday’s Observer, “if there are extraterrestrial civilisations out there, they don’t seem very interested in us. They don’t visit, they don’t phone, they don’t even send radio signals. Not a peep.”
But what if they could communicate but just choose not to? The silence from space might, after all, be that of a galactic-scale Meeting in progress. Thinking of it that way changes the nature of what we are hearing, perhaps.
