This is a splendidly comprehensive view of cataclysms both cosmic and terrestrial. Despite coming in with a fairly serious science background, I learnt a great deal and was fascinated in doing so.
However - and this is a personal preference - I have never liked Bob Berman's populist style. It comes across as frivolous.
Just one example, picked at random. "Here, ten billion years after the final episode of Friends and fully eight billion years after even the last reruns of it, our sun is now the central star of a planetary nebula." One can imagine being amused by a speaker throwing in such a light-hearted comment in a serious speech just to provide a contrast to the audience.
Alas, this approach actually typifies the entire book and only the occasional serious comments provide any contrast. Given his success as author, media personality, astronomy tour leader etc. (and he is not shy of informing the reader about this during the book), it appears there is a big audience for this style. It just doesn't include me.
I am full of admiration for his knowledge and I am significantly wiser as a result of reading this book. I'd just be feeling a lot happier if he had toned down the frivolity.
