The epic, behind-the-scenes story of an astounding gap in our scientific knowledge of the cosmos.  

In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is complet

Now this is how an honest-to-goodness popular science book ought to be like. The book basically tracks the same story as A Universe from Nothing by Lawrence M. Krauss and even has Lawrence as a character every now and then. Because I was familiar with the story and its ending, this time around I could concentrate on the telling of the story more than the actual events themselves and I was struck by the high contrast of how Richard Panek handles the material and how Krauss had presented it in his ...more

What a very strange book this is, and what a very strange guy Richard Panek seems to be. I know many autistic-spectrum people, and I wonder if he isn't a little autistic. One of the most characteristic things about autistic people is the unevenness in their range of abilities. They are usually extremely good at some things and staggeringly incompetent at others. Panek is definitely a bit in that direction.

Panek sets out to tell us about the most recent chapters in the exciting history of cosmolo

This was another book that ended up being sold on false advertising. Now, you might be forgiven for thinking a book called the 4% universe is going to be about, well, cosmology or something crazy like that. This was mostly about the infighting between groups of cosmologists and as such it goes to prove that a physics degree is no protection from being a wanker. The cosmology, far too often, comes second.

This is a superb look at the one of the principle mysteries of modern science: that the observable universe is dominated by matter we can't directly see (dark matter) and a bizarre unexplained force that drives the expansion of the universe (dark energy).

The book is broken down into three main parts, the first part looking at the origins of the science of cosmology and discoveries around the existence of other galaxies, the expansion of the universe and the cosmic background radiation. The secon

I've been on something of a science kick lately. This is my third science-based audiobook this year, and it's only early April. I've enjoyed them all, even if I can't say that I understood everything in them. This book, though, felt like a desert triathlon compared to the other two leisurely strolls in the park. This book was exhausting. But I say that in the best way possible. I think.

First, let me just say that this book is seriously fascinating. I love astronomy and cosmology, so I'm fascina

This is really an enjoyable, easy-to-read book on the recent history of cosmology. Read this book and you will understand the big questions in cosmology--there are no answers yet. I especially appreciate the descriptions of recent advances in astronomical observation techniques, and the telescopes (optical and radio) that are used. I thought that a bit too much of the book is devoted to the competition to find and measure supernovae, and the squabbles that ensued.

I have a lot of respect for this book, but after reading it (and rereading large portions of it), I was unable to retain anything from it. First, it is primarily the story of the scientists behind the recent advances in cosmology and the search for dark matter and energy, and without the benefit of any character development, I was unable to keep anyone straight. I could not recount any of the story of discovery, the teams involved, or the people that won the awards, as there is not much establis ...more

This is a deeply frustrating book to read because Panek took no time to craft an overall meta-analysis to tie together all of the elements of his story. This is a subtle point and I will try to briefly explain what I mean below. I am all the more frustrated because the story of dark matter and dark energy, however the scientific understanding plays out in the future, is absolutely fascinating. But upon reflection, I have to issue what is perhaps the most damning verdict that can be passed on a b ...more

This is an attempt to tell the human story behind the discoveries that led to our modern conception of the universe being made up mostly of dark energy, plus about 25% dark matter, and finally about 4% in the form of the matter and energy that we can directly detect, including ourselves. In addition, Panek goes some distance toward explaining in simple terms some pretty abstruse cosmological concepts.

So far, so good. I read the book for relaxation as much as anything else, and at that level I ve

For 20 years or so after the first Star Wars movie came out, most people who mentioned "dark" and "universe" in the same breath were talking about Darth Vader and the Dark Side. Doubtless some of the movie's fans were also astronomy fans who'd heard about the evidence for real dark matter -- not what it is (nobody yet knows what it is) but what it does, flattening galaxies, speeding up their rotation, and invisibly sculpting the structure of the visible night sky. Yet the import of that particul ...more

The 4-Percent Universe The 4-Percent Universe begins with the story of the discovery of cosmic microwave background radiation in 1964 by Bell Labs employees in Holmdel, New Jersey. This isn’t what I was expecting, but often science books set the stage with a little history as a prelude to the science. The next chapter? ... More history.

This year, the 2011 Nobel Prize in physics went to three men--Saul Permutter, Brian Schmidt, and Adam Riess--for their discovery of what 96% of the universe is composed of: dark matter and the much more elusive, dark energy. Does anyone really know what these things/entities are? No, but they do make up the majority of the cosmos and dark energy appears to be responsible for the fact that our universe is neither static (as Einstein thought) nor are its boundaries beginning to collapse (as might ...more

A very readable history of the discovery of dark matter and dark energy, including brief biographies of the scientists involved. Particularly, it illuminates how the pressures of being a human being afflict those who are gifted intellectually and pursue astronomy and physics just as much as us more ordinary types who can't balance our checkbooks and can only recognize the Great Dipper constellation.

By the last chapter in the book, this will make sense to you: "In early 2010, the WMAP seven-year

A funny thing happened to me on the way to.... seriously, this book was given high marks by two friends. I tried listening to it, and abandoned the effort after 3 (out of 9) discs. A lot of the time, I could follow but then had no idea what it was that I had just heard. And sometimes I couldn't follow at all. And occaisionally (but not frequently enough), I understood it perfectly. So not a great experience.

I don't consider the two star review a qualitative measure of "4 Percent Universe", so much as an indication that it failed to deliver what I expected. It is exceptional as a series of biographies of the scientists involved in the search for dark matter, dark energy, and supernovae; it is passable as a layman's course on modern cosmology and the techniques that are being employed; but it falls far short of being a useful study on dark matter and dark energy themselves. These concepts don't even ...more

This book was a disappointment. While it begins with a flourish, and introduces the reader to the notion of dark matter and energy, it quickly digresses into a manual of academic politics between rival labs. It would have been better to stay with the development of the so-called "missing" mass in the universe, or inferences from redshift/blueshift observations of the dynamic universe. The key word in the title of this volume is "the race to discover" rather than the discovery itself. This book i ...more
This book focuses on the history of the discovery of dark energy and dark matter.
It provides a sufficient if not dry survey of historical astronomy in the first half.
The second half goes into some of the yummy meaty details of the arguments for these two dark mysteries.
Though, the last chapter of the book digresses into a history of ugly bickering over who discovered dark energy.
Richard Panek obviously has a bone to pick, and it's a disgusting waste of the reader's time.
My advice is to just skip

Best history on Vera Ruben that I have read to date. That alone made this a 5 star book.

This elementary introduction to the discovery of dark matter is easy to understand, well written, provides a really nice history and would serve as the perfect book to read in preparation for more difficult books on the subject (e.g. Cosmic Cocktail, A Perfect Theory, Dark Matter and the Dinosaurs, Gravity's Engines, Warped Passages, Particle at the Edge of the Universe, The Infinity Puzzle, etc).

A remarkable book, allowing the uninitiated into easy comprehension of developments over time that led to current beliefs about the universe. It is almost like reading an action novel as a variety of worker bees announce new discoveries, competing against each other and against time. I have tried and failed to read about quantum theories, getting easily lost. This book manages to take us live into the action and dialogue over the years as theorists, astronomers, cosmologists present papers and s ...more

This spring I read the non-fiction book by Rickard Panek with the alternative title, “Dark matter, dark energy and the race to discover the rest of reality”. Pretty big title and the mystery still is what the rest of reality is. But he did cover the race to discover it between a group of physicists and astronomers which in the process birthed the science of cosmology. Read the epilogue first. In there on page 242 Panek says, “In early 2010 . . . the results arrived bearing the latest refinements ...more

This is now the third or fourth book I've read on the modern history of cosmology, particle physics, etc. I keep hoping that if I read enough of them, I'll eventually catch on. Some I learned in the book (which I dearly hope are reasonably accurate, even if garbled in writing):

* Only 4% of the universe is actually observable. The rest is dark matter and dark energy.

* I had heard before that there wasn't enough observed matter in the universe to keep it from imploding (exploding?), but I hadn't r

Science written by a science writer who gets the facts all right; the universe is vast and galaxies are many, but the breathlessness and wonder of the decades-long sprint are missing. Facts are dry, although when 96% of the universe is stuff we cannot see and know nothing about, facts are sparse in the sky. I expected more juice from a title that includes "race" in it. That's my issue. The book is good reportage. I was looking for the brilliant light shed by Carl Sagan's awestruck "billions and ...more

Exploring "one of the most important stories in the history of science" (Washington Post), Panek nimbly outlines recent findings in physics, astronomy, and cosmology and evaluates rival theories in clear, comprehensible language. He also dives into the bureaucratic morass and professional enmities of contemporary research, examining how these discoveries were made as well as who made them. While some critics appreciated this behind-the-scenes human drama as a tool for understanding the full stor ...more

This is an interesting look at modern cosmology, and the perplexing fact that scientists can only account for about 4% of the universe's matter. Another 21% or so is "dark matter", so far rather poorly understood, and fully 75% is "dark energy", that strange characteristic of the universe that is causing it to expand at an accelerating rate. Panek also describes the "cosmological constant" paradox, namely the fact that the energy density of the universe is 120 orders of magnitude lower than the ...more

Hard to know who the audience for this book is supposed to be. Insufficient explanation of the science means most non-specialists will only be able to follow the history of cosmology as it is developed in the book in the most trivial way. While at the same time the thumbnail character sketches of the working scientists are too short and too bland to provide much of additional interest. Panek is also a surprisingly boring stylist.

I just finished this, and I realize now that he wrote this to describe (as the title clearly indicates) the "race" more than to describe the science.

Now, I realize that he accomplished exactly what the title suggests... and I'll go looking for another new book on particle physics or dark energy or...

This read more like a biography of the scientists behind cosmological discovery than it did about dark matter and dark energy as universal concepts/theories in general, but I think what I found to be most interesting is how so-called 'simple answers' about the universe have proven themselves to be winding, circuitous, and at times, downright contradictory. Where lambda was concerned, for instance, also known as the cosmological constant, there was so much uncertainty about whether it should hold ...more

I think that I am going to have to stop reading popular science books by journalists. I like to read science books to learn about science, but I didn't get that here. Most of the science was a rehash of what I already knew, and I don't know much about dark matter and dark energy. The lives of the scientists can be interesting, and some scientists are fascinating characters. Certainly Einstein and Feynman were unique people, and I have been interested in the lives of Hawking, Heisenberg, Dirac, a ...more
