So I am going back and reviewing some of the books I have read previously. Have to be honest here, The Elegant Universe and Fabric of The Cosmos were great books, but I am kind of drawing a blank on this one. I know I read it, but apparently it did not make a last impression.

But that said, when I read the first two books I was clueless about Quantum Mechanics and I learned quite a bit through those books.

while the book is based on the newest physical and mathematical theories, most of multiverses are full of universes that repeat themselves an infinite number of times or vary very little. I believe that NATURE HAS AN INFINITE VARIETY: There are an infinite number of universes, each is different , infinite and eternal.

Physicist Brian Greene is one of the best popular science writers, and in this third book (also in audio), he explores the idea of parallel universes and what they might look like in a way that non-scientists can (mostly) understand. This is all theoretical and conceptual science, but intriguing speculation on various multiverse-based explanations of reality.

He's the best writer on the subject -REALITY -out there. His earlier book, The Fabric of the Cosmos is also awesome. The Hidden Reality gets you as close to the leading edge of theoretical physics as you can get -short of sitting in on a graduate seminar.

While this is a good book, I believe everything was explained in the comic book, Fantastic Four, issues 52-54, titled "Subatomica" - - i.e., our universe is actually a neuron in someone's brain (god?), while universes reside within our own brains, our own neurons - - ergo, the multiverse!

This is a good, mostly readable essay on the new physics.

This book is about the different theories in physics that come to the conclusion that we are part of a multiverse. Each chapter focuses on a specific theory such as M-Theory, String theory or the Endless Doppelgänger theory which all expound upon the idea that there are parallel universes out there. The book was exceptionally well written. The author is very good at making extremely difficult and complex theories easily comprehendible. Highly recommended for anyone interested in the subject!

Could our entire awareness be no more than a simulation, as in The Matrix?
Are there other universes barren of biological life? Or is there no universe other than our own?
Maybe.
