The idea of a multiple universe reality is no longer considered speculative or implausible by many physicists; rather, it is deemed inescapable. Distinct concepts of the multiverse spring from quantum mechanics, cosmology, string theory-based cosmology, and ideas about a mathematics based reality that borders on the religious. In this accessible and entertaining book, Dr. Manly guides you on a tour of the many multiverse concepts and provides the non-technical background to understand them. Visions of the Multiverse explores questions such Dr. Manly discusses a wide variety of fascinating concepts from relativity and the fundamental particles and forces of nature to dark matter, dark energy, and quantum mechanics in an unintimidating and conversational tone. Is humanity is in the midst of a new Copernican revolution? You decide.
Not so interesting if you had already read other multiverse books. Like Brain Greene's Hidden Reality.
If you only read Max Tegmark's mathematical universe, then it's more worth it to explore.
While I agree with this book's better classification of the different types of multiverse, it takes most of the book to introduce the basic physics of QM, particle physics and GR, cosmology to beginners.
Too little time spent on actually describing and exploring the different types of multiverses.
I came to this book out of blind curiosity about the concept of a multiverse. What I got was a thoughtful overview of concepts and the scientific context for them. The author is clearly a teacher, because he's able to deliver the material in an accessible way. I tried starting another book on the multiverse concept and it was so dense I gave up by page 5. This was the perfect introduction and primer. It felt like I got maybe 2/3 to 3/4 of the way through this book before descriptions of multiverse concepts emerged, and as someone who never studied physics, I found the book was still plenty dense. But it's also clear and fascinating. As a result, I found I can now understand science news about the cosmos, like recent reports of Einstein's Cross/multiple appearances of a distant supernova, and recently disproved 'evidence' of cosmic inflation. And I get more of the references dropped during reruns I catch of the Big Bang Theory.
