argent_ 's review for:
A Universe from Nothing: Why There Is Something Rather Than Nothing
by Lawrence M. Krauss
Unsurprisingly, a wonderful book by Krauss. The complexity of the topics he talks about varies from relatively elementary stuff (if you are a science literate) to concepts I know I'll need to reread a few times before I have a firm general idea what's going on.
My only problem - and this was the main reason I bought the book - was his deepest and most controversial idea. He claims that given only a theory of quantum gravity, our (and every other) universe could spawn out of complete nothingness, and each universe that spawns could have its own laws of physics. Which I am fine with, but it still feels to me like the quantum gravity he assumes to be preexisting is one of those laws - so where did that come from?
But other than that, everything else has been a really nice read. At times it gets a little bit too (theoretically) technical, but then I don't think this book is meant to be read by people who lack even a basic scientific education. So it's all good.
