What If?

by Randall Munroe

What If?

Randall Munroe

Overview

What do you think would happen if someone threw a baseball at 90% the speed of light? Do you know how fast you can hit a speed bump and still live? Or have you ever thought about how much force Yoda actually outputs in Star Wars?

If you've ever wondered what would happen if some of the craziest and most impossible events actually happened, you're not alone. What do you get if a former NASA roboticist opens up his website to field wacky questions and answer them with science? That's where Randall Munroe comes in. He is the author of the webcomic xkcd, which also hosts his "What If?" platform. Anyone can submit any question they can think of to his site, and Munroe uses real scientific principles to answer his favorites.

A few years ago, some of the best questions and answers were compiled into a book called What If?: Serious Scientific Answers to Absurd Hypothetical Questions. If you like science and you like humor, you're going to love this one.
