To start negatively, I was slightly disapointed after reading this book. Was expecting a bit more on this big and mystical subject that is "origins". But being a very difficult subject, I would still rate the book as a 4 stars because I still learned a lot from reading it and the style of writing of the authors is enjoyable.
Theories and concepts are well explained and abordable by the amateur reader.
This book ir recommended. It was very entertaining and informative. I found some chapters a little difficult because there were too many topics, I think that with subsections on the chapters would be more easy
No being from a science background, NDT is the best author for breaking down galactic sized occurrences in a way that you can understand and also keeping you smiling throughout. This is an amazing book.
