This is a bunch of scenes from Carl Sagan's Cosmos series (miss you, Carl!) remixed to make a song. It is awesome. Plus, Stephen Hawking laid down some phat vocals, so it's double sweet. Like eating a scoop of birthday cake ice cream and a scoop of birthday cake batter ice cream AT THE SAME TIME. Except not that good because there's nothing better than that.

Thanks to Paul, who has traveled to the far ends of the cosmos and verified that Geekologie is, in fact, the best website in the universe. Also, the man's seen alien snatch.
