“Their laudable goal is communicating vast, cosmic ideas in ways that are accessible without being simplistic.”—Washington Post“Learn about everything from the birth of the Universe and quasars to dark energy and exoplanets from three of the coolest guys you’ll ever meet.”—Annalee Newitz, Ars Technica“Riveting questions fielded by three top astrophysicists in engaging style. . . . They may just have produced the best book about the universe in the universe.”—New Scientist“As citizens of the cosmos, we are duty bound to explore it. So opine astrophysicists Neil deGrasse Tyson, Michael Struass, and Richard Gott, guides on this bracing expedition through dusty galactic hinterlands and the vast theoretical vistas of Albert Einstein’s work.”—Nature“All three [authors] write in informal, conversational tones, and the text is sprinkled with genuinely funny non sequiturs, such as a brief rumination on dwarfs versus dwarves and commentary on English-speaking aliens in Star Trek. . . . What the book does very well is to present not just what we know about the universe but how we know it.”—Science
