I've long enjoyed Randall Munroe's xkcd comic for years and am now interested in his 'What if' website. Here, he takes questions on a variety of subjects and offers thoughtful answers as well as humourous commentary. His background as a NASA employee gives him the credentials for hard-science questions as displayed in the first question he answered: What if a pitched a ball at nearly the speed of light. He described what would happen - nuclear powered destruction for all nearby - and also pointed out that the (now vaporized) "batter would be considered hit by pitch and would be eligible to advance to first base."
Suddenly, I want to take hypothetical questions here. Indeed, could you imagine a world where you couldn't ask hypothetical questions?
