Tolle Lege!.

There is not a wasted concept in this book. The author explains everything you need to understand about time and why he thinks it is real and how modern physics has taken it out of the equation. He starts with defining mathematics as the study of the unchanging. Math (in the Platonic/Western Thought way) is how how we sneak timelessness into our way of thinking about the universe. The Newtonian paradigm adds to taking time out of the equation by the way we always must consider a subset of the universe as a whole and we are the observers and we create the time, but the part under study never covers the whole universe. Time is external to that which is under study.

The author explains "Boltzman's Brain" so that I finally understand what it means and why it's important, he explains entropy, entanglement, the standard model and Einstein's General relativity and how they relate to how we take time out of the model.

This book will forever change the way I think about time. I think it is probably the best of all the 50 or so astrophysics/cosmology/physics books I've read and reviewed over the last 2 years.

I highly recommend listening to this book. The narrator knew exactly when to have the mocking laugh, the inflection and so on. I suspect the author worked with the narrator to make the presentation that flawless.

(p.s. At the core of this book lurks the question "why is there something instead of nothing". I just listened to Holt's book "Why does the world exist". It's mostly a philosophical book, but both this book and that book do complement each other and would make and excellent summer read).
