Sean Carroll has written an interesting physics book. I like reading about physics, the logic of explanations is elegant, as long as I don't have to contend with my weak point, math. He does a good job of bringing that about and the story is fascinating. The question of the arrow of time has been a problem for physics for a long time, because everything at quantum level says it should be reversible. But, that is different from what we see in the real world. Is there some emerging phenomenon that arises once we leave the ultra small and go macro? No according to the author. He takes the question of time and relates it to entropy and arrives at the big bang, black holes and ultimately the multiverse. If such topics interest you then by all means get this book, but if physics gives you headaches don't. I thought it was worthwhile to get a better grip on the subject, but I am not going to put it into the recommended reads, although he does tackle some skeptical subjects.
