I am a lay person who reads a great deal of books about time and general/special relativity. Unfortunately, I was duped into buying this book by the reviews on the back of the book and the snazzy cover.However, the author simply rambles on and on and on, and never presents any scientific or mathematical proof that his theory is correct. This is quite simply the worst book on this subject that I have ever read. The "End of Time" has reinforced my position that I will never again buy another book in a bookstore without first having read the reviews on Amazon.com
