WHAT IF you still had so many more strange questions about the universe?

And WHAT IF Randall Munroe, former NASA roboticist and xkcd creator, were prepared to move mountains, fill the solar system with soup and alter the space-time continuum to answer them?

Whether it's how to make a lava lamp out of lava or feeding the inhabitants of New York to a T. Rex, welcome to the weird, wonderful (and sometimes terrifying) world of WHAT IF? 2

Industry Reviews

Praise for What If?

What If? maintains a delightfully free-wheeling tone throughout, especially when complicated calculations lead to whimsical results. Despite all the hard facts and gigantic numbers, it never feels like a textbook-and you don't have to be a rocket scientist to enjoy it - ENTERTAINMENT WEEKLY

The best bathroom book you'll ever buy...Munroe takes inane, useless and often quite pointless questions asked by real humans (mostly sent to him through his website), and turns them into beautiful expositions on the impossible that illuminate the furthest reaches, almost to the limits, of the modern sciences .The first chapter, "Q. What would happen if the Earth and all terrestrial objects suddenly stopped spinning, but the atmosphere retained its velocity?" ends with the anthropomorphized moon worrying over the state of the Earth, and, with the gravity generated by its own rotation around the Earth, saving our dying planet. The physics are real; so is the emotional content. . . The answers are all illustrated with xkcd's trademark stick figures.. . . . and these are eminently approachable - NEWSWEEK

What If? includes old favorites, new inquiries and the mix of expert research and accessible wit that has made Munroe a favorite among both geeks and laymen - TIME

XKCD is nerd royalty, the alpha dork, there's no geek more widely cited and loved - BEN GOLDACRE, author of BAD SCIENCE

Dangerously absorbing . . . if you have ever been gripped by an insatiable, preposterous intellectual curiosity (regardless of actual scientific knowledge), I could not think of a better book to keep you from doing that essay for an extra hour or two - Varsity
