“Mind-blowing. . . . If [Randall is] correct. . . . it would be a revolution in human thought every bit as gargantuan as that precipitated by Copernicus. — House of Speakeasy Blog

“The nature of the impactor remains unknown, but if it was indeed a comet dislodged from the Oort Cloud, then Randall’s book provides an entertaining and radical explanation of the events leading up to their ultimate extinction.” — On Being with Krista Tippett

“[Randall’s] is a fascinating, tantalizing theory, linking life on Earth-or the extinction thereof-with the very origins of our universe.” — Publishers Weekly, Starred Review

“Engrossing in its own right, this theory opens onto an illuminating survey of the cutting-edge science now deployed to test its components, including its daring redefinition of dark matter. As she did in Warped Passages (2005) and Knocking on Heaven’s Door (2011), Randall delivers intellectual exhilaration.” — Booklist, Starred Review

“Writing in a deceptively chatty narrative style, Randall provides a fascinating window into the excitement of discovery and the rigor required to test and elaborate new hypotheses. A top-notch science book from a leading researcher.” — Kirkus, Starred Review

Only Lisa Randall can take us on such a thrilling scientific journey―from dinosaurs to DNA to comets to dark matter and to past and future of our species. Randall’s research is so thorough, the story so powerful, and her storytelling so compelling that I could not put this book down.” — Siddhartha Mukherjee, author of Emperor of All Maladies

“The nature of the impactor remains unknown, but if it was indeed a comet dislodged from the Oort Cloud, then Randall’s book provides an entertaining and radical explanation of the events leading up to their ultimate extinction.” — Walter Kirn, author of Blood Will Out and Up In the Air

“The wonder and curiosity Lisa Randall so obviously feels about our world and the universe itself is evident on every page. [Randall] render[s] complex subject matter into a gripping page-turner that is impossible to put down. Dark Matter and the Dinosaurs is a fascinating, mind-expanding experience.” — Augusten Burroughs, author of This is How and Running with Scissors

“Lisa Randall has produced an intriguing, insightful book that brilliantly weaves together the disparate subjects of cosmology and biology. . . . A simple, elegant theory that finally makes sense of mass extinctions. A must read for anyone interested in the precariousness of life on earth.” — Jack Horner, MacArthur Fellow and author of How To Build a Dinosaur

“Dark Matter and the Dinosaurs is . . . a masterpiece of science writing: a detective story that illuminates the nature of scientific research while explaining how our very existence may be connected to unexpected properties of the dark matter that fills the universe.” — Kip Thorne, Feynman Professor of Theoretical Physics at CalTech

“A provocative and revealing account of how scientists like herself are uncovering deep connections between human existence and the wider universe. A terrific read.” — Timothy Ferris, author of Coming of Age in the Milky Way and Seeing in the Dark

“World-renowned physicist Lisa Randall brings a fresh twist to one of the world’s oldest murder mysteries, the death of the dinos. With lively writing and wonderfully accessible explanations, she now convincingly implicates a new suspect as ultimately responsible for the hit: a novel kind of dark matter.” — Max Tegmark, physicist and author of Our Mathematical Universe

“It’s a tall order to cover everything from the Big Bang to today’s ongoing Sixth Extinction in a consistently engaging way for a general audience. Particle physicist Randall delivers, peppering serious science with anecdotes about Roombas and fortune cookie messages.” — Discover Magazine

“By grounding one in the principles of cosmology, particle physics, geology, astrophysics, paleontology and meteoritics, Randall provides the reader with a broad spectrum look at not only the world around them, but the worlds around that world, the galaxies and galactic clusters, filaments, sheets and, eventually, the Universe.” — Paste

Bestselling author of Warped Passages and Knocking on Heaven's Door and one of today's most influential and highly cited theo-retical physicists, Professor Lisa Randall once again effortlessly delivers fascinating science to the general reader. Weaving together the cosmos' his-tory and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cata-clysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.

With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.

In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.
