In this book, Munroe answers unusual and often absurd hypothetical questions sent by readers, using scientific reasoning, mathematics, and physics to explore their consequences. The questions range from the fantastical—like hitting a baseball pitched at 90% the speed of light—to practical curiosities, all tackled with humor, clarity, and detailed calculations. The book is an extension of his blog "What If?", where these answers were originally posted, accompanied by his signature xkcd-style stick figure illustrations.

The book and the blog have been well received for making science approachable and entertaining, mixing serious science with absurd premises to offer unique learning experiences and laughs. A sequel, "What If? 2," was released in 2022. Additionally, "What If?" has been adapted into a video series, further expanding its reach. In summary, "What If?" is a quirky, science-based exploration of hypothetical questions authored by Randall Munroe, blending humor, science, and popular culture to captivate curious readers.
