So far, SETI (Search for ExtraTerrestrial Intelligence) has been a total bust: a complete and utter waste of time and money. And that's great! Imagine you have an actual nuclear bomb sitting around in your office. What is the most fun (and manly) thing to do with it? Preferably without killing yourself... Considering the size and age of the universe we should be up to our eyeballs in aliens. But nobody is bothering us here at home. What gives? What's the difference between a nuclear blast and a potato cannon? As it turns out: Not that much when you are doing it right.
