In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times bestselling author of Warped Passages and Knocking on Heavens 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 findingsestablished and speculativeregarding 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....

Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe Reviews
Randall is the first to warn her reader that her new hypothesis is speculative and in need of more testing. However, she is excited about the kinds of questions this new direction is taking her. Randall has been investigating how dark matter might be involved in not only the creation of matter itself, but possibly in the evolution of humans as well. The presence of dark matter is not at all speculative. It has been detected using a variety of tools and methods. What is speculative is the notion ...more
I've been reading a new book called Dark Matter and the Dinosaurs by Lisa Randall, Professor of Particle Physics and Cosmology at Harvard.
Here's my take-away from that. (The speculation is my own, not hers.)
The Edge of Our Existence
Reach out and touch something. Go ahead, do it. Not mentally or figuratively, but literally, really. Done that?
You just reached through space that is 26 orders of magnitude more nothing than something.
Space is far more empty than we realize. We are told that air has ...more
So far, I've appreciated Randall's explication of dark matter and her graphics that demonstrate the history of the cosmos. But much of it feels like a leaden rehash of cosmology-for-laypeople that I've read before.
Spellbinding Account of Cutting-Edge Physics, Astrophysics and Geology
Noted theoretical and experimental physicist Lisa Randall offers a spellbinding account of her current research into dark matter and how it relates to other cutting-edge science in astrophysics and geology in her latest book, “Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe”. This is a riveting exploration into how science in done, describing in ample detail not only her research, but also nota ...more
1. DARK MATTER AND THE DINOSAURS. (2015). Lisa Randall. ***1/2.
The author is a professor of Science at Harvard, and studies particle physics and cosmology. She already has several books under her belt that deal with various aspects of her fields of study in a popular manner. The main subjects of this book are dark matter and dark energy, and their potential effects on life on Earth as we know it today. It is amazing to me that ordinary matter – that matter that we can see and interact with – onl ...more
This is a very informative read.
1. Dark matter is an invisible substance that scarcely interacts with the rest of the universe through any force other than gravity. Whatever dark matter is, astronomers have inferred there is quite a lot of it by watching how large-scale structures respond to its gravitational pull.
2. Dark matter seems to constitute almost 85 percent of all the mass in the universe, and it is thought to be the cosmic scaffolding upon which galaxies coalesce. Many theories, in fa ...more
Delicioso. O conteúdo é um pouco especulativo no final, quando ela defende o argumento central do livro (sim, o argumento central é especulativo), que a matéria escura poderia matar dinossauros. Mas a explicação toda para chegar nesse ponto é boa, bem descrita e compreensível. É o tipo de atualização de área que a astronomia precisa, com o que vem acontecendo de novo na área, de energia escura à matéria escura. Recomendadíssimo.
Sixty-six million years ago another day dawned over a Cretaceous earth. Life was carrying on as normal, but everything was about to change because heading towards the planet at an astounding speed was a ten-mile wide object. The impact of this object left a crater, traces of which can still be detected and managed to obliterate the dinosaurs and 75% of all the other species on the planet. The few that survived evolved into the huge variety that we have today and provided an opportunity for the m ...more
