Carroll explores what our intuitive understanding of time is, and how physics in the form of relativity and thermodynamics offer a deeper understanding of how time's arrow arises. Beginning with the simple observation that eggs can be made into omelettes but omelettes can't easily be made into eggs, Carroll takes us on a scientific roller-coaster all the way to the multiverse.
Brief Answers to the Big Questions is a wonderful collection of the late Stephen Hawking's musings on the "Big Questions". Not everyone will agree with all of his views, but it's difficult not to be inspired by the cosmic journey Hawking transports you through, and the heartfelt optimism he has for the future of humanity.
If we do wish to take the theory seriously, as we should since it is so powerfully accurate, then we are led to the Many-Worlds Interpretation as the most "face-value" interpretation.
This book is a collection of Hawking's thoughts and reflections on ten "Big Questions" touching on the existence of God, the origins of the universe, and the future of the human race. Not everyone will agree with Hawking's conclusions, but his engaging prose and novel ideas are certainly worth the read.
