| Comet/Asteroid Impacts and Human Society: An Interdisciplinary Approach
by Peter T. Bobrowsky (Editor), Hans Rickman (Editor)
In 1908 an atmospheric explosion in northern Siberia released energy equivalent to 15 Mton of TNT. Can a comparable or larger NEO affect us again? When the next NEO strikes Earth will it be large enough to destroy a city? Will the climate change significantly? Can archaeology and anthropology provide insights into the expected cultural responses with NEO interactions? Does society have a true grasp of the actual risks involved? Is the Great Depression a good model for the economic collapse...

Product Description
The dark matter problem is one of the most fundamental and profoundly difficult problems in the history of science. Not knowing what makes up most of the mass in the Universe goes to the heart of our understanding of the Universe and our place in it. In Search of Dark Matter is the story of the emergence of the dark matter problem, from the initial 'discovery' of dark matter by Jan Oort to contemporary explanations for the nature of dark matter and its role in the origin and evolution of the Universe. Written for the intelligent non-scientist and scientist alike, it spans a variety of scientific disciplines, from observational astronomy to particle physics. Concepts that the reader will encounter along the way are at the cutting edge of scientific research. However the themes are explained in such a way that no prior understanding of science beyond a high school education is necessary. |

A little light on dark matter by Ramesh Gopal (Albuquerque, NM United States)  3 Stars
March 22, 2009
The title of this book caught my attention because so-called Dark Matter is an important and puzzling issue in modern astronomy. In brief, the stars we see have insufficient mass to account for the gravity of galaxies and galactic clusters. The missing mass must reside in non-luminous, i.e. Dark Matter.
This book starts out promisingly enough. Ken Freeman and Geoff McNamara do a good job of framing the question and explaining how astronomers found a discrepancy between the amount of visible matter and the observable gravitational effects. After the first few chapters the book loses its way. It becomes more of a survey of the ideas on the subject rather than an effort to choose between them and present a coherent point of view. It is clear that ordinary matter in the form of protons, neutrons, electrons, etc is not present in sufficient quantities to explain the gravitational effects. Something else with a specific distribution that can be inferred from astronomic observations must account for the remaining gravitational effects. This leads to somewhat vague discussions of the possible mass of neutrinos, black holes (massive and small) and of exotic particles like WIMPS (weakly interacting massive particles) and axions. At the end of it all the authors are not inclined to share with us where their preference lies. Instead, they divide the missing mass into Hot Dark Matter (HDM) and Cold Dark Matter (CDM). The difference between them is poorly explained, but at the end the authors tentatively come down on the side of CDM, albeit with caveats. Judging by the tenor of the last few chapters they seem to feel that they have provided a satisfactory account.
The last chapter is actually the best because it is co-authored by Charles Lineweaver, who himself being a contributor to constraints on the cosmological constant is willing to take a clear stand. Unfortunately, this is also the point where it is revealed that in terms of the cosmological constant (omega) baryonic matter accounts for 0.04 of the contents of the universe, (cold) dark matter for 0.27 but a huge 0.73 is Dark Energy (the total being close to the desired 1.0). Dark energy barely gets and discussion. Although this preponderance of dark energy should come as no surprise to the interested layman who has kept up to date with developments in astronomy, it does seem to beg a whole different book with another title.
Notwithstanding the closing paragraph's self-congratulatory but ambiguous remarks, readers will want to go in search of dark energy.

An EXCELLENT book on Dark Matter by Eric B. Norris (Santa Clara, California USA) 5 Stars
May 10, 2007
This book sets out the evidence for missing matter in the universe in an entertaining yet thorough way. There is virtually no math in the entire book, and yet each subject area is treated fully. I had thought the first evidence for dark matter was star rotation rates in galaxies as set out by Vera Rubin and others. However this book traces the roots of the "something is wrong with our picture of the universe" back to the 1930s and Fritz Zwicky and Jan Oort--two astronomers who could not be more different from each other. And that is another strength of this book--we learn something about Zwicky and Oort without being seriously sidetracked.
"In Search of Dark Matter" strikes a perfect balance between moving the story along (and it does read like a story) and stopping here and there for brief asides about the personalities and milieu involved at the various stages of dark matter research. Finally, alternatives such as MOND theory are discussed. This book is not a deep tome--it is only roughly 150 pages. But it certainly piqued my interest and made me want to find out more. The authors succeed in bringing up most topics assuming little or no background in astronomy, yet don't get mired explaining the basics. A great read!

| Dark Side of the Universe: Dark Matter, Dark Energy, and the Fate of the Cosmos
by Iain Nicolson (Author)
Once we thought the universe was filled with shining stars, dust, planets, and galaxies. We now know that more than 98 percent of all matter in the universe is dark. It emits absolutely nothing yet bends space and time; keeps stars speeding around galaxies; and determines the fate of the universe. But dark matter is only part of the story. Scientists have recently discovered that the expansion of the universe is speeding up, driven by a mysterious commodity called dark energy....

Everyone knows that there are things no one can see, for example, the air you're breathing or a black hole, to be more exotic. But not everyone knows that what we can see makes up only 5 percent of the Universe. The rest is totally invisible to us. The invisible stuff comes in two varieties—dark matter and dark energy. One holds the Universe together while the other tears it apart. What these forces really are has been a mystery for as long as anyone has suspected they were...

| Dark Matters: Unifying Matter, Dark Matter, Dark Energy, and the Universal Grid
by Dr. Percy Seymour (Author)
One of the most important unsolved problems of current physics, astronomy, and cosmology is the nature of dark matter and dark energy. These two invisible components of the universe seem to control the behavior of galaxies, clusters of galaxies, and the accelerating expansion of the universe, but we do not know what they are. Dark Matters offers a unified explanation for dark matter and dark energy, and, in doing so, formulates a new theory of ordinary matter.
