I've always thought this is the answer to "where is everybody?". Up until now, we've been looking in the radio spectrum for messages. Radio waves only travel at light-speed; so it'd be a pretty crummy means of interstellar communization. We're already on the verge of instantaneous communication via quantum entanglement (sometimes rather confusedly called teleportation). Perhaps when we latch on to whatever communication method might be out there we'll find the "airwaves" flooded with extra-terrestrial transmissions.
lolololol...NPR.....idiots.
