What If? 10th Anniversary Edition: Serious Scientific Answers to Absurd Hypothetical Questions - Hardcover

Randall Munroe answers absurd questions using real physics. Updated with new material for 2025. What if you tried to hit a baseball pitched at 90 percent the speed of light.

The charm is that the questions are genuinely stupid and the answers are genuinely rigorous. What if everyone on Earth stood as close together as possible and jumped at the same time. What would happen if you were to go to the sun during the daytime and collect sunlight in a container. Munroe works through the physics with diagrams and humor, and you learn something about how the world actually works.

Physics teachers assign excerpts in class to show that physics is everywhere, even in jokes. Engineers and scientists read it because it validates the pleasure of asking dumb questions rigorously. It's also genuinely funny, which is rare for a math book.
