A message carried by the Voyager 1 spacecraft, the first manmade object to enter interstellar space. This message will last about a billion years.
If humans descend into mass self-destruction, then the messages, images, and music contained on the golden record affixed to the side of Voyager 1 will be all that is left, in the entire universe, of who we are as a species.

“These Roman Numerals are the offshoot of classical typography and architecture; the stems become Ionic columns; the shoulders, semicircular arches; and the crossbars, friezes. Between them, they also work as modules to play with and create small constructions. Symbolically, in the same way that the objective of mathematics is to discover the universe, so numbers are the bricks that form that universe.”
"Through an old but serviceable telescope from our front yard…my father showed me the moon and the planet Saturn for the first time, and I shall never forget it…seeing those objects up close changes you, and so it was with Professor Sagan’s astronomy class. It has changed me every bit as profoundly as the craters on the moon or the rings of Saturn. He empowered us. Indeed, he emboldened us to come to know our place in the cosmos, our place among the stars — what I like to call our place in space. Every day in his class, there was something astonishing to behold." - Bill Nye
