4.0 étoiles sur 5 Create a Universe in Your Own Basement 28 juin 2004
Par Joshua Koppel - Publié sur Amazon.com
Format:Poche
I just finished reading Gregory Benford's COSM. The book was good (as usual) and sort of followed a path similar to that in ARTIFACT in that you have some characters trying to learn about a mysterious object.

An ambitious, young physicist is running an experiment on RHIC (Relativistic Heavy Ion Collider) using streams of elliptic uranium. At first everything is fine but then the readings seem to slow down. Suddenly there is a massive explosion. Amidst some of the wreckage is a reflective sphere about the size of a bowling ball. The physicist knows this has something to do with the explosion and takes the sphere for observation. Unfortunately she is a little too secretive and charges of theft and impropriety are raised.

The sphere is an enigma. It feels solid but doesn't seem to be made of anything. It has no spectrum. Light can penetrate is slightly. It emits photons as if it were at four-thousand degrees. It seems to have a tidal effect near the surface. What is this object? The physicist teams up with a theorist to try and solve the mystery. But as the mystery becomes clear bit by bit, the political and scientific climates intensify. Finally, a theory is arrived at that seems to take into account all of the facts. The object is a pocket universe with an internal time that is accelerating.

Soon the sphere becomes transparent and the birth of galaxies can be witnessed. As time speeds up in the sphere, now called a Cosm, it becomes more and more important to continue observations. But as the experiment demands closer inspection and more time, the charges against the physicist also demand more time. Although the physicist warns against it, the Brookhaven Lab repeats the experiment and creates a much larger Cosm. Unfortunately this one is too big to move and is obstructing repairs to the RHIC. The story's threads all build and collide in an ending that brings about a number of interesting questions about the nature of our own universe.

COSM is a very good novel that Gregory Benford first had the idea for in the late 1980s. A number of theories, studies, and publications are mentioned in this novel and they are all real. Even if you are not a promising particle physicist the story is very easy to follow. The characters all seem to act consistently and I found no obvious flaws that detracted from the novel. If you like hard science that is located right on the edge of current research then I would strongly recommend COSM.

5.0 étoiles sur 5 Hard core physics in fast paced credible SciFi thriller 7 juillet 1999

As a woman PhD physicist, who worked in academia and government labs, I REALLY identified with Benford's black superwoman, superhero, hard-nosed but soft hearted physicist, who is too busy teaching and making her name in science to get a love life (which, true to life, comes to her eventually through working on physics with fellow physicists).The science fiction flows smoothly out of science fact, the coast- to-coast settings and characters are all too familiar and true to style in this near-term future, whether it's the UC or Caltech faculty, students and administrators, or whether it's at the Brookhaven accelerator; and federal officials are still the BAD GUYS. As a Benford fan of long standing, I found this novel to have more depth, more character development, more plotline and more fun: it's a good read for all and any science or SciFi lovers...I give it an easy high five!

4.0 étoiles sur 5 Not the usual Science-Fiction fare.... 4 décembre 1999
Par Russell Wild - Publié sur Amazon.com
Format:Poche
An original, believable novel about a small-particle researcher who discovers a strange, new object during an experiment with a particle accelerator. Hell...that sounds like a story-line only a hard-core geek could get off on....but Cosm is a very entertaining book in a genre which...if it hasn't grabbed me in the first twenty pages....I give it the flick. I read the whole 370-odd pages...(and that hasn't happened since Sagan's "Contact") The dialog is a strong point...witty, in parts down-right funny. There are no long winded rambles on the nobility of researchers delving into the unknown for totally self-less reasons etc...but the laboratory techniques of a working researcher are believable (to this reader at least) and some fascinating ideas about the evolution of our universe are conveyed; information on the working lives of the scientific community, particularly those involved in small-particle research is convincing. Greg Benford has put in the hard yards of research before he put pen to paper here. A darn good read.
