"Space," Douglas Adams observed in his comic sci-fi novel "The Hitchhiker"s Guide to the Galaxy," "is big. Really big. You just won"t believe how vastly hugely mind-bogglingly big it is. I mean, you might think it"s a long way down the road to the chemist, but that"s just peanuts to space." So, in his fictional universe, Adams invented the Infinite Improbability Drive as a way to cross its vast distances in a nothingth of a second. And, in one memorable passage, to convert two approaching nuclear missiles into a bowl of petunias and a sperm whale. Thus, today"s image of the Earth"s largest toothed whale is our tribute to Adams on the 20th annual celebration of Towel Day (it"s surprisingly difficult to find a really great image of a bowl of petunias).
