How to Build a Time Machine
How to Build a Time Machine by Paul Davies is a 2002 physics book that discusses the possibilities of time travel. It was published by Penguin Books.
Synopsis
In this book, Davies discusses why time is relative, how this relates to time travel, and then lays out a "blueprint" for a real time machine. This is explored whilst also discussing paradoxes which allow a more constructive approach. It is a realistic, albeit fantastical, book.
In Kirkus Reviews the reviewer noted that this volume allowed "Davies to wax eloquent on concepts he has covered in earlier works: general relativity, quantum mechanics, black holes, virtual matter, parallel universes, as well as assorted time paradoxes."
