I won't pretend to understand even 10% of the book, but I get the gist: we'd better have parallel universes (multiverse), or we'd be screwed!
Seriously - what Brian Greene means is that all the mathematics point to the necessity of a multiverse, which is the only way to reconcile all the equations, observations, theories, etc. This book describes the various types of multiverse that are consistent with what we know so far, but as confirmation is still hopelessly beyond our capability, the true picture is still hidden to us - hence the book's title: The Hidden Reality....Continua
I used to read the books of Stephen Hawking and Carl Sagan with great interest. But after reading 50+ pages this book still doesn't turn me on. I'd rather abandon it to save my time for other books!
It is quite obvious that more and more physicist are converted and come out of the closet.... to support, proof and embrace the multiverse. It is no longer so weird ideas from Dr Frankenstein. It is highly possible alternative explanation of quantum theory.
There are a lot of different possible way to have multiverse, it get stranger and stranger when you proceed...
And... it is highly possible that, after this wandering of this absurbly vastness and timelessly long period of time, we can get back to us. At least the mild Anthropic explanation is now more or less accepted. Maybe, it is true that inside us, you can find the whole universe, even multiverse. Since, we are all one....Continua
Check out what I wrote in my blog:
10-13-2011: Finished finally! Not very easy to understand, but very nice to read. I finished it with big effort, but I don't think that I got a lot of the things he said. However, I am looking forward to reading something else of this author in the near future.
08-05-2011: I am trying hard to keep up with all the equations and mathematical explanations, but I have been about to give up. However, somewhere around chapter five, the author gave me the opportunity to skip some pages, and I did promptly and found out that the next set of pages was very entertaining and understandable. In sum, I am still struggling with this, but not yet abandoned it.
I am still in the process of reading this book. It has been a nice surprise to be able to understand and follow the author's line of thought. He tries to prove that there are parallel universes, and that there are more than the three dimensions that we are used to live in....Continua
This time, I don't feel that I have learnt as much from the author as in his last book ("The Fabrics of the Cosmos"). Probably because it's "just" all about the multiverse and string theories. It's an interesting and well-organized compilation of all the possible Multiverse scenarios though with some (disproportional) biased emphasis on the string theory. In this book, the author has tried quite hard to convince the readers that the theories that can't be tested in near future are not completely worthless. Being a string theorist, the author obviously sometimes put the string theory on par with relativity and quantum mechanics almost as if he wants to create an illusion of the string theory being as well tested as the relativity and quantum mechanics, though we know that he doesn't really think so nor intend to....Continua
