It's like a book for the public but I'm afraid only the experts can fully appreciate and comprehend most of the contents. To me, the biggest appeal of Conformal Cyclic Cosmology (CCC) is that it provides a smooth transition between the previous aeon to the present aeon of our Universe. It's a brave idea that I've probably never heard of. The CCC mechanism may take away some of the violence of the Big Bang. The author is really conveying his challenging ideas to the experts. It's like a hugely extended paper to promote his ideas of the CCC. The possibility of observing some signatures of the previous aeon is mind-boggling and very appealing. But near the end on p. 205, he suddenly uses as much as a figure (Fig. 3.22) to explain that the radius is a reciprocal measure of curvature, which seems like out of place, because if the readers don't know about this and the readers probably don't know anything before p. 205.
On p. 194 at the last line, "back hole" should be "black hole".

I loved this book because it explains a new revolutionary theory about how our universe is built. However, I would be lying if I said that I read it all. Actually I had to abandon it after trying to give all my attention to part 1. Part 2 and 3 looked packed with graphics and complicated formulas, and I simply don't have time for them. But don't get me wrong: the fact that I am unable to read it doesn't make it a less wonderful book; and I liked it for that.
