WHAT IF?: Serious Scientific Answers to Absurd Hypothetical Questions

I'm not a person that is that much into physics/science, but this was quite a fun read! The author makes it understandable, even if you don't have a scientific background and covers a range of fun questions.

A really good insight in how things could probably work, but practically it would be either not possible or a high risk for the human life. Also good to read if you don't have such a big concentration, because the chapters/questions are mostly answered in about 4-5 pages.
