This is the Evpatoria message. It was beamed out from earth via a radio telescope, with the intent that extraterrestrial intellegences would be able to read it. Anyone who recieves the message will have built a radio telescope, so while we cann't rely on the recipent knowing English, we do know that they must understand physics and thus mathematics. Are you a sentient being? If you are, you should be able to decode this message... (Drag to select symbols, then decide what they mean.)
