Space at the Speed of Light is an awesome book. It is decently easy to understand with a conversational prose. Dr. Smethurst's prose is engaging and I can sense her enthusiasm as I read the book. The book itself was intriguing throughout and never dry. I also liked the variety of concepts that it went over. When I first came across the book, I thought it would be solely a history of the universe. While it does contain a good amount of information about this, it goes far beyond. It talks about black holes, the possibility of aliens, the likelihood of finding another Earth, what we've learned about other galaxies and stars, dark matter, and much more. In the end, it left me inspired to both learn more and appreciative of how amazing our universe is. It is such an incredible place and there is so much that we don't know (and that makes it even more interesting).
The explanations provided in this book are more high-level, but, again, they made me want to learn more in detail.
I recommend this book :).
