The mind often wanders — drifting to strange ideas, bizarre notions, and ridiculous questions — most of which you've probably dismissed or never found answers for. But What If?: Serious Scientific Answers to Absurd Hypothetical Questions doesn't just let those questions go. Instead, it explores well-researched answers to some of the weirdest quandaries you've ever thought of. Questions like: How fast can you hit a speed bump and survive? How long would humanity survive a robot apocalypse? All of the answers are based on extensive military research, computer simulations, differential equations, and in-depth interviews, making it both thorough, and thoroughly ridiculous.
