Our Mathematical Universe: My Quest for the Ultimate Nature of Reality

Like an ostrich with its head in the sand, we humans have repeatedly assumed that all we could see was all that existed, hubristically imagining ourselves at the center of everything.

This book was a good broad intro to various modern cosmological ideas mixed with the author’s personal experiences and philosophical takes. For a broad overview, the book was excellent.

The middle section was most compelling. In this section, the author described four types of parallel universes which could possibly exist based upon what we currently know. These are thought-provoking possibilities and fun to imagine. These four types are described below:

As an aside, one of my favorite out-of-context quotes from the book is below—

To the bird, reality is the geometry of the pasta.
