Colossal flows of galaxies, large empty regions called voids, and other unexplained phenomena offer clues that our own "bubble universe" could be part of a greater realm called the multiverse. How big is the observable universe? What it is made of? What lies beyond it? Was there a time before the Big Bang? Could space have unseen dimensions? In this book, physicist and science writer Paul Halpern explains what we know—and what we hope to soon find out—about our extraordinary cosmos.

Explains what we know about the Big Bang, the accelerating universe, dark energy, dark flow, and dark matter to examine some of the theories about the content of the universe and why its edge is getting farther away from us faster Explores the idea that the observable universe could be a hologram and that everything that happens within it might be written on its edge Written by physicist and popular science writer Paul Halpern, whose other books include Collider: I have to start by heartily agreeing with a statement from Space Review: Halpern displays throughout this book.

He takes you from early theories to the latest, identifying and crediting the researchers by name as the theo It has been many years since I enjoyed a scientific book as much as this one. He takes you from early theories to the latest, identifying and crediting the researchers by name as the theories are presented.

They fit in as if characters in a novel, playing their part. As theories are changed, no aspersions appear, just a healthy respect for the different people and what they could prove or what their revelations led to.

Edge of the Universe A Voyage to the Cosmic Horizon and Beyond

Halpern makes it seem like you could understand anything in astrophysics, etc. There is no condescension, but an acceptance of the reader as an equal who is just not knowledgeable in this particular area. Delightfully, the notes at the end of each chapter allows the reader could follow up more details if desired. The analogy use is probably not unique to Halpern, but the success of the model guarantees the success of the book's goals.

A pretty high achievement for a teacher who must communicate only through the written format. I may not be ready to pass a test on the book, but I am very pleased with it, and the fact that Halpern makes it possible for me to be proud of myself for being able to understand such material. Halpern is a gifted writer who gifts the reader with an intelligent understanding of this material.

I never thought I would be able to understand so much without a vast knowledge of mathematics. Thank you so much, Mr. Halpern, for this book. I probably didn't say this as succinctly or in as polished a manner as I'd like. But I hope my enthusiasm and appreciation for it show through brightly. Jan 16, Samy Rose rated it it was amazing. Sep 25, Nilesh rated it liked it. Edge of the Universe is a good, understandable summary of where cosmology and science are as of today. It focuses on the findings of the last decade or so, which are stunning. More importantly, the discoveries are subverting some of the cherished conclusions of accepted theories at the universal scale at least.

The book goes beyond dark matter and dark energy to even discuss non-homogeniety of space including dark flow, galaxy voids and clusters, and many other phenomena which are in extremely ea Edge of the Universe is a good, understandable summary of where cosmology and science are as of today. The book goes beyond dark matter and dark energy to even discuss non-homogeniety of space including dark flow, galaxy voids and clusters, and many other phenomena which are in extremely early stages of their discovery.

It is quite possible that some of these findings are challenged or improved comprehensively in future. Or alternatively, new theories are developed to explain what is going on. As a result, the book is a good update at a point in time - today in and around It does this job as good as anyone. However, given the focus of the book, it will be superseded soon by events and more findings in the next few years. All that said, the book conclusively shows how what we thought were near-complete theories of relativity and quantum physics are in the need for massive changes to explain cosmology.

Apr 14, Ant Ryan rated it it was amazing. What can I say - this is scientific outreach at its best, in the best arena of science - physics. Paul Halpern's book not only explores beyond the horizon of observation, but makes the subject of cosmology within everyone's reach. He does this in a fun, non-condescending way, which unlike many science writers makes the reader feel included in the journey the book takes.

On this Universal voyage, we encounter Dark matter and Dark energy; imagine what could be behind these significantly influential, yet largely unknown phenomena, before navigating our way through higher dimensions and across the Multiverse.

In addition to all the accurately, concise information, we find ourselves learning about the cosmos in a fun way, with everyday references and analogies. The book oozes the author's enthusiasm for the subject.

I hope and expect this book will make a strong impact and whet the appetite for Cosmology to many more amateurs like me and pure novices alike, and judging from advance praise from the books previewers, Paul's professional peers also think the book is wonderful. This is a great book for helping understand the "BIG" and "small" theories about the cosmos. Very readable but more importantly enjoyable.

A lot of the topics are difficult to comprehend but Halpern does an amazing job of breaking them down and using everyday analogies. Throughout I was impressed how he explained the integral relationships of Quantum theories and the study of the Universe and its origins, providing the average reader with a better understanding of the contemporary theories. I h This is a great book for helping understand the "BIG" and "small" theories about the cosmos. I highly recommend it for the reader looking to get a potent introduction to Cosmology.

Feb 25, Ripu Jain rated it really liked it Shelves: If you enjoy cosmology like i do, you will enjoy this book. Its not as eloquent as stephen hawking books, or as understandable as NDT would describe concepts, but it does a good job at explaining the latest in cosmology and our understanding of it. From 16th century astronomy to holographic principles, from theories on beginning of universe to different models of universes end, from quantum to infinite, from blackholes to multiverse, this book covers pretty much all the topics and the scientists If you enjoy cosmology like i do, you will enjoy this book.

It is a heavy read, and definitely not for beginners, but cosmology enthusiasts will find this mind boggling. May 05, Ob-jonny rated it really liked it. Such an entertaining and informative book about astrophysics. It's a great feeling to have a good understanding of dark matter, dark energy, and dark flow and to know the theories of the causes of each. The discussions of the possible futures for the cosmos are interesting too and it was gratifying to learn about the big rip, the big stretch, the big crunch, and the big freeze. I also think it's really cool that Stephen Hawking's initials are written in the billion light-year long letters in the Such an entertaining and informative book about astrophysics.

I also think it's really cool that Stephen Hawking's initials are written in the billion light-year long letters in the microwave background radiation of the universe. Dec 23, Talbert Houle rated it it was ok. The information on worm holes and dark matter were the most interesting parts of the book. After that, I was bored by it. Granted, I knew this book might be a stretch since I am only mildly interested in cosmology, and since this book was a lot of "the history of Dec 26, Jake rated it liked it.

An excellent overview of Modern Cosmology and Quantum Physics. Could have used a bit more detail Re: Susskind's expansion of Holographic Theory and informational sub-space, overall a good read though. Feb 04, Holly rated it it was amazing Shelves: This was such a fantastic book. It was incredibly engaging and the information presented was so very cool and exciting. I love books about the universe, quantum mechanics, physics, and all the other science fiction-y things related to it.

This is like real life science fiction and it's awesome. Oct 27, Giulia Paris rated it liked it. Got into too much details about chemistry at the end but the rest is pretty good. The beginning is great and puts together a lot of the latest theories about the universe.

Pretty complete coverage of findings in cosmology. Analogies are not always the best--but then again the physicists just don't have a complete understanding. Jan 31, Hugo Rodrigues rated it liked it.
