The book showed great evidence and facts and the author did that to prove a point to the reader. A thing I really like about this book was it was long, all the space books I read are short but this book you can take your time and read more. Another thing I liked is when the author put a time line and Glossary, The Glossary really helped me with the words the writer put in the book. All these detailed facts and evidence really blew me and made me believe that the big bang was real.
