Note: This is such a brilliant piece, we are breaking with tradition and posting this xkcd comic today rather than wait until EarthDesk Sunday. — John Cronin
xkcd is the webcomic creation of Randall Munroe, an extraordinarily popular web presence whom we feature regularly on EarthDesk. He draws on science themes often and has been nominated for a Hugo Award twice, thanks to his loyal science fiction fan base. He enjoys creating different ways of looking at our planet. But you know that by now.
The xkcd website is here.
