1.0 out of 5 stars
DO NOT BUY THIS BOOK!!, May 31, 2006
This review is from: Comprehending and Decoding the Cosmos: Discovering Solutions to Over a Dozen Cosmic Mysteries by Utilizing Dark Matter Relationism, Cosmology, and Astrophysics (Paperback)
There are many reasons why Jerome Drexler's theory of dark matter is not widely accepted amongst astronomers. I am a professional astronomer working at a research establishment in California. The idea that relativisic protons can be responssible for the dark matter of the Universe seems ridiculous to me and this is why:
1. If dark matter consisted of relativistic particles (such as relativistic protons) then this is what astronomers would refer to as Hot Dark Matter. Hot Dark Matter has been ruled out as a form of dark matter because it does not allow the structures we see in the Universe. The reason because the particles are at such high velocities that they can never become gravitationally bound to each other, and all structure is wiped out. Galaxies cannot form, stars cannot form, planets cannot form. This would be a huge problem. This is why astronomers have come to believe in Cold Dark Matter (slow moving massive particles).
2. Protons are charged particles (they have positive charge). Any moving charged particle has both an electric and a magnetic field associated with it. Relativistic charged particles would create a huge electric and magnetic field. This would be easily observed. However, it has never been observed.
3. The Cold Dark Matter Particle (the WIMP) has never been observed for a reason. It's predicted mass lies just beyond the energies we can probe with our current particle accelerators. The next generation of particle accelerators will be able to probe these energies. These new particle accelerators will be coming online in the next 2 to 5 years, so watch this space. Admittedly, if we don't find the predicted WIMP (or neutralino as it is strictly called), then we do have to go back to the drawing boad.
I don't understand how this book has come to be published. The people deciding it should be published are obviously not professional astronomers. However, Jerome Drexler has never had his theory published in an astronomical journal. The reason is because it has never made it past the peer review stage... because his theory is simply WRONG. It does not stand up to experimental tests or what we know about the Universe.

This is just BAD pseudoscience, nothing more!, November 11, 2010
This review is from: Comprehending and Decoding the Cosmos: Discovering Solutions to Over a Dozen Cosmic Mysteries by Utilizing Dark Matter Relationism, Cosmology, and Astrophysics (Paperback)
I am a professional astronomer, and my research is in theoretical astrophysics, so naturally I try to keep an open mind, since there is much we do not know (keeps life interesting)! There are numerous issues in cosmology and physics in general which we do not understand, but we are working on those problems. Science works by small increments. Someone comes up with a theory or two, we test it and see what works and what does not. Jerome Drexler is advocating a theory THAT HAS BEEN DISPROVED! We know that dark matter is NOT relativistic protons. However, using science-like arguments that have NO REAL SCIENTIFIC BACKING, Drexler purports to solve a bunch of cosmological problems all at once! This is nothing more than pseudoscience. As a scientist, it's upsetting that people might actually believe him. Real scientists spend all their lives to try to understand and explain how the Universe really works, and then someone such as Drexler comes along, publishes his own book (yes, it was self-published), and tried to push a view that NO SINGLE SCIENTIST would agree with! The only reason I even reviewed this book was at the request of the librarian at my institution. The head librarian told me that Drexler had sent all 4 books to the library as a gift. The librarian was rather skeptical about these, and asked me to look and see if they have any scientific merit. They do not!
There are numerous reasons why Drexler's work is simply wrong. "Dr Marc" (first review) touches upon a few of them. By the way, the Sun is well known to be approximately 4.5 billion years old. Drexler claims it's over 13 billion years old! If I came up to you and would argue non-stop that you're 3 times older than you really are, what would you think? You would think "what's wrong with this guy!" Well, Drexler is basically arguing about the same thing. We know the age of the Sun, but Drexler thinks we got it wrong. Basically everyone since Newton through Einstein and beyond got it wrong, but he got it right... so, are alarm bells ringing in your head? They should! Please, do not spend money on this book. There are lots of good books and articles written by professional astronomers/physicists that I would highly recommend, but as for this book, AVOID IT!

Poses questions; posits answers, October 20, 2006
This review is from: Comprehending and Decoding the Cosmos: Discovering Solutions to Over a Dozen Cosmic Mysteries by Utilizing Dark Matter Relationism, Cosmology, and Astrophysics (Paperback)
Drexler's book was sent to me unsolicited inviting my feedback and comments. I cannot call myself even an amateur cosmologist therefore I cannot assess how plausible the explanations in this book are. Furthermore, I have not actually read it cover to cover. Nevertheless, I award it 4 stars for the following reasons:
1. The topic is well laid out and is made very accessible via extremely short chapters listed in a detailed table of contents. It is well indexed. A glossary is also included.
2. Throughout the book, use is made of lists, both bulleted and numbered, e.g. pp 110-114, making it easy to follow his arguments.
3. More importantly, it lists 58 references (7 to his own work) as well as a further 30 suggested sources. Readers are cautioned not to assume agreement in these sources with Drexler's views.
4. The book is intended to be provocative and to generate further thought and discussion. The Preface states: "This book, "Comprehending and Decoding the Cosmos," deviates significantly from mainstream cosmological and astrophysical theories."
I would not, of course, recommend a book just because of its layout and style. I see this book as a thought-provoking re-examination of existing observations and theories in addition to offering solutions and new ideas. I leave it to others to comment on the plausibility of these.
