by Lisa Randall
In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times bestselling author of Warped Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth.
Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.
Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.

Starred review from September 7, 2015
Using accessible writing and vivid examples, Randall (Higgs Discovery), a theoretical particle physicist and cosmologist at Harvard University, examines the indirect role dark matter may have played in the extinction of the dinosaurs, as just one example of the unlikely connections to be found in the universe. She builds her argument methodically, moving from discussions of the big bang and galaxy formation, through prehistoric extinction events, and into the way dark matter interacts with other forces and particles. Scientists detect dark matter indirectly, Randall says. In space, a massive object bends light as it zips past, so that object’s mass can then be determined by measuring the bend. Its gravity can also perturb the motion of other bodies passing through the area. Randall proposes the existence of a dense disk of dark matter inside the galactic disk of the Milky Way. As stars—including our sun—rotate around a galactic center, they and their planets cross the dark disk. On Earth’s pass-through, the dark disk’s gravity could have perturbed an icy rock in the Oort Cloud, sending it on a collision course with Earth. Randall covers a lot of ground, but does so smoothly even when addressing some of science’s most abstruse subjects. Hers is a fascinating, tantalizing theory, linking life on Earth—or the extinction thereof—with the very origins of our universe. -

Dark matter: it's hard enough to understand as it is, and now Randall draws on original research to suggest a new kind. But as author of the recent New York Times best-selling Knocking on Heaven's Door, Harvard physicist Randall can talk to the less scientifically proficient. Here she theorizes that the huge comet that purportedly knocked out the dinosaurs and perhaps three-quarters of Earth's other species 66 million years ago was shaken from its orbit as the solar system passed through a disc of dark matter embedded in the Milky Way. With a 100,000-copy first printing.

Starred review from September 15, 2015
To explain the disappearance of the largest land animals the earth has ever seen, Randall probes something that has never been seen: dark matter. More specifically, this acclaimed physicist argues that it was dark matter that nudged a comet earthward, so wiping out the dinosaurs 66 million years ago. As Randall unfolds the reasoning behind this bold speculation, she traverses an impressive range of science. Readers learn of the decisive role that dark matterundetectable except for its gravitational pullplayed in shaping galaxy clusters. They also learn about the dynamics of our own solar system, where our planet's remarkable powers to sustain life may grow or diminish through the impact of objects from space. Widely publicized evidence that such an impact exterminated the dinosaurs gains astonishing new significance as Randall reinterprets it within her theory of how a disk of unusually interactive dark matter, insinuated in the heart of the Milky Way, unleashes a shower of meteoroids every 32 million years. 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.(Reprinted with permission of Booklist, copyright 2015, American Library Association.) -
New York Times Book Review
"Successful science writing tells a complete story of the 'how'-the methodical marvel building up to the 'why'-and Randall does just that." — New York Times Book Review
"A cracking read, combining storytelling of the highest order with a trove of information on subjects as diverse as astrophysics, evolutionary biology, geology and particle physics. What's remarkable is that it all fits together." — Wall Street Journal
"The universe, Randall eloquently argues, is an organic thing, a symphonic thing, with all its myriad parts contributing their own notes." — Time Magazine
"Randall succeeds in guiding the reader through the history of the cosmos and the Earth from the Big Bang to the emergence of life as we know it in a fun and captivating way. . . . [This is] a very enjoyable read for both lay readers and scientists." — Science Magazine
"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." — Philadelphia Inquirer
"Through Randall's brilliant research we see a universe unfold that is far grander than anyone at any time could have imagined... She is a progressive thinker, a visionary capable of bridging the vast gulf between speculation and reality science." — San Francisco Book Review
