A collection of essays on the cosmos, written by an American Museum of Natural History astrophysicist, includes "Holy Wars," "Ends of the World," and "Hollywood Nights."

According to astrophysicist Tyson, director of New York City's Hayden Planetarium, size does matter when it comes to black holes, although the chances of your surviving the encounter aren't good in any case. Tyson takes readers on an exciting journey from Earth's hot springs, where extremophiles flourish in hellish conditions, to the frozen, desolate stretches of the Oort Cloud and the universe's farthest reaches, in both space and time. Tyson doesn't restrict his musings to astrophysics, but wanders into related fields like relativity and particle physics, which he explains just as clearly as he does Lagrangian points, where we someday may park interplanetary filling stations. He tackles popular myths (is the sun yellow?) and takes movie directors--most notably James Cameron--to task for spectacular goofs. In the last section the author gives his take on the hot subject of intelligent design. Readers of Natural History magazine will be familiar with many of the 42 essays collected her
