If I were an alien and I listened to these human greetings, I would totally freak out and destroy Earth. Fortunately, the original Voyager's Golden Records don't have that creepy background noise, just the voice of humanity and Gaia's sounds.
The disc—which is included in the Voyager I and II spacecrafts—contains 116 images, animal sounds, the sounds of Earth's elements, music from different styles and times, and the greetings you can hear on this video, spoken in 55 languages. They were selected by a NASA panel headed by none other than legendary astronomer Carl Sagan.
This video—created by Claire L. Evans—pairs the warm greetings with the skies of their countries of origin, as if these people were shouting at the stars. Claire says that she did it to highlight our loneliness, and the herculean task of SETI.
It will take forty thousand years for Voyager I to be within 1.6 light years of another star, after leaving the Solar System: AC+79 3888 in the Ophiuchus constellation.
Loneliness indeed. [The Daily Dish]
