為了求出答案，蘭德爾‧門羅進行電腦模擬、挖出已解密的軍事研究紀錄、請教核反應器的操作人員、用碼錶為「星際大戰」電影的場景計時、打電話問他媽媽，還用Google搜尋一些看起來很恐怖的動物。本書從xkcd網站中挑選出最熱門的問題，但也加入很多全新內容（約51％）。

例如，你會知道，
以接近光速投出的棒球，可能會夷平整個城區；
一莫耳的鼴鼠，可能會使行星窒息於一層肉當中；
電影「星際大戰」裡的尤達大師，可以用原力來幫電動Smart車充電。
從「遇見你的靈魂伴侶」到「以真正元素來建立週期表的種種死法」，
蘭德爾‧門羅都以令人捧腹大笑、佩服不已的答案，
為我們解釋一切。
歡迎來到《如果這樣，會怎樣？》的異想世界。
From the creator of the wildly popular webcomic xkcd, hilarious and informative answers to important questions you probably never thought to ask.
Millions of people visit xkcd.com each week to read Randall Munroe’s iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate
following.
Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent the speed of light? How fast can you hit a speed bump while driving and live? If
there was a robot apocalypse, how long would humanity last?
In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators.
His responses are masterpieces of clarity and hilarity, complemented by signature xkcd comics. They often predict the complete annihilation of humankind, or at least a really big
explosion.
The book features new and never-before-answered questions, along with updated and expanded versions of the most popular answers from the xkcd website. What If? will be required reading for
xkcd fans and anyone who loves to ponder the hypothetical.
