What If: Serious Scientific Answers to Absurd Hypothetical Questions

I really like xkcd and the What If? section Randall does on there, so this being the same, but in book form seemed like an easy win.

There are lots of interesting scientific answers to questions that just must be asked, like “What would happen if you tried to hit a baseball pitched at 90% the speed of light?” or “If every person on Earth aimed a laser pointer at the Moon at the same time, would it change color?”

I enjoyed this one, but wouldn’t say it blew me away.
