The Big Picture: On the Origins of Life, Meaning and the Universe Itself

Sean Carroll’s 2016 book, The Big Picture, is a rather well-succeeded attempt to cover all the topics that are listed in the subtitle of the book, life, the universe, and everything.  Carroll calls himself a poetic naturalist, short for someone who believes physics explains everything but does not eliminate the need for other levels of description of the universe, such as biology, psychology, and sociology, to name a few.

Such an ambitious list of topics requires a fast-paced book, and that is exactly what you get. Organized in no less than 50 chapters, the book brings us from the very beginning of the universe to the many open questions related to intelligence, consciousness, and free-will. In the process, we get to learn about what Carroll calls the “core theory”, the complete description of all the particles and forces that make the universe, as we know it today, encompassing basically the standard model and general relativity. In the process, he takes us through the many things we know (and a few of the ones we don’t know) about quantum field theory and the strangeness of the quantum world, including a rather good description of the different possibilities of addressing this strangeness: the Copenhaguen interpretation, hidden variables theories and (the one the author advocates) Everett’s many-worlds interpretation.

Although fast-paced, the book succeeds very well in connecting and going into some depth into these different fields. The final sections of the book, covering life, intelligence, consciousness, and morals are a very good introduction to these complex topics, many of them addressed also in Sean Carroll popular podcast, Mindscape.
