With several best-selling books under his belt, along with multiple service awards and honorary doctorates, Tyson has become one of the most popular science spokesmen since Carl Sagan, whose famous Cosmos miniseries Tyson rebooted for 13 episodes in 2014. In his latest work, Tyson offers a breezy but scientifically grounded overview of his primary field of expertise, astrophysics, skillfully tailored to increase lay readers’ understanding of topics such as the big bang and relativity in time to better appreciate the next astronomical discovery or blockbuster science-fiction movie. Twelve bite-size, lucidly written chapters cover the fundamentals of inflation theory, gravity, dark matter, black holes, and the surprising reasons planets and suns are round. Tyson also gives star billing to some of science’s most famous innovators, such as Newton and Einstein, dissecting how they developed their signature theories. A final, elegiac chapter extols the virtues of having a cosmic perspective to lighten the burdens of living. Even readers normally averse to anything to do with physics or chemistry will find Tyson’s wittily delivered explanations compelling and disarmingly entertaining.
