A bit deep at times but fascinating nonetheless,
By
This review is from: The Book of Universes (Hardcover)
This is a book more about the history of theories about what constitutes a universe rather than a book about what we currently believe the current state of our universe is although that is covered to some extent. Barrow describes theories that have fallen by the wayside, such as universes expanding in different ways in different places, or not having begun with a "bang" at all. Through this it becomes apparent that any theories propounded today are just as likely to be "boshed" in years to come as we are at the very boundaries of science and the experimental method. John Barrow is a very readable author, bringing life to potentially baffling and complex ideas and although some old ground is gone over (quantum theory etc) it doesn't do any harm to reinforce all these ideas as I for one still don't quite always "get" it. Whilst Brian Cox's latest tome is "lighter", has better pictures and diagrams and is an excellent book in its own right, I would encourage anyone who has read that to look at this one and put some meat on many of the bones that Prof Cox describes

BOOK OF UNIVERSES,
By
This review is from: The Book of Universes (Hardcover)
Once one appreciates that Einstein's equations of General Relativity permit many resonable solutions, one grasps the enormity of the 'multiverse'. And enormity is the apposite word when vacuum states of the string landscape are consisered. This is a very good book written by an expert researcher in cosmology; he just happens top be a good writer too! Not much in the way of mathematics - probably a good thing in a semi-popular book. Nonetheless, clearly articulated and, in my view, better than Brian Greene's latest offering. Thoroughly recommended.

better than Greene's book,
By naivetheorist - Published on Amazon.com
This review is from: The Book of Universes (Kindle Edition)
If you enjoy the speculations of theoretical physicists on the nature of the universe, then Barrow's book is a better book to read than Greene's "Hidden Realities". The only thing that surprises me is that both of these authors waste space and time (or is it space-time?) on the simulation idea of Bostrom since it makes absolutely no contribution to the topic. Penrose's new book is also a fun read as is the book by Bojowold. Be aware that these 'ideas' fall outside the realm of real science and (probably) have no chance of ever being tested but they are a fun read on a lazy afternoon with a drink in hand.
