Apparently our radio broadcasts can be listened to in a “space bubble” 200 light years in diameter. That’s huge! But when you compare it to the rest of the Milky Way, um, not really. So just know when you’re hoping an E.T. will find you through your radio broadcasts, he has to be within that bubble to hear you. God, we’re so insignificant. [jacakadamblog via Geekosystem]
