In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand. Written with exceptional style and clarity, Three Roads to Quantum Gravity confronts the deepest questions of the nature of the universe and provides a preview of some of the remarkable scientific developments we can look forward to in the 21st century.

Overall fine audio book
Listening to this audio book was an overall good experience. It was good to finally find a popularizing book offering an alternative quantum gravity theory (other than string theory) . However, this book is mostly about this theory (loop quantum gravity -lpg) and does not cover the other two theories the title suggests on equal footing. This was actually good for me since I was ignorant about lpg and was already familiar with string theory. Also since there is much less popularization and followers of this theory I would have liked a longer and more detailed book. Regarding the content, the author offers a convincing argument about a background independent quantum gravity theory and highlights the relational nature of general theory of relativity. Despite the apparent bias of the author towards lpg, which he acknowledges as a cofounder, I appreciated that he emphasized that these theories still remain incomplete and at best well motivated speculations in the absence of experimental evidence as of today. The narrator was pretty good too.
