God and the Multiverse: Humanity’s View of the Cosmos by Victor J. Stenger
“God and the Multiverse" traces the history of humanity’s view of the cosmos and examines how that view has changed over the last ten thousand years to the present. Sadly, Dr. Stenger passed away before the release of this book in which he makes use of disciplines within physics to present plausible scenarios for a natural origin of our universe and though more speculative infers that our universe is but one of an eternal multiverse that contains unlimited number of other universes. This provocative yet challenging 447-page book includes the following sixteen chapters: 1. From Myth to Science, 2. Toward the New Cosmos, 3. Beyond Unaided Human Vision, 4. Glimpses of the Unimagined, 5. Heat, Light, and the Atom, 6. The Second Physics Revolution, 7. Island Universes, 8. A Dynamic Cosmos, 9. Nuclear Cosmology, 10. Relics of the Big Bang, 11. Particles and the Cosmos, 12. Inflation, 13. Falling Up, 14. Modeling the Universe, 15. The Eternal Multiverse, and 16. Life and God.
Positives:
1. A well-written and well-researched book.
2. An interesting topic, humanity’s evolving understanding of the cosmos.
3. Dr. Stenger has a great command of the topic and tries his darndest to keep it accessible.
4. The book’s emphasis is on science. That is a focus on observation and experiment than theory. “If a model agrees with the data, then it has something to do with reality.”
5. Plenty of graphs, illustrations and charts to assist the reader.
6. Provocative. “Short of divine revelation, for which no evidence exists, I know of no method by which we can determine what is ultimately real. The best we can do is make ever-improving observations and describe them with ever more accurate models.”
7. The interesting and often times difficult interaction between religion and science. “They also tried to deal with Psalm 93, which declares that the foundation of Earth remain forever unmoved, and other biblical contradictions. Rheticus wrote a tract attempting to rectify Copernicus with holy scripture, but it was never published.”
8. Far-out facts. “From these and other observations, it has been determined that luminous matter—the stars and hot gas we see in the sky by eye and instrument—constitutes a mere 0.5 percent of the total mass of our universe.”
9. Contributions from the great scientists of the past and present throughout the book. “Einstein also predicted that a clock in a gravitational field runs slower, as observed by someone outside the field. This is called gravitational time dilation and is derived directly from general relativity. This effect is also well confirmed. If the GPS in your car did not correct for gravitational time dilation, it would not always take you to where you want to go.”
10. Does a great job of chronicling the history of astronomy by highlighting the most note-worthy developments in cosmology. “Then, in January 1913 he obtained his result: The spectrum of Andromeda was blue-shifted, that is, shifted to shorter wavelengths. Assuming the mechanism was a Doppler shift, Slipher calculated that Andromeda is moving toward us with a speed or radial velocity of 300 kilometers per second.”
11. An interesting look at the big bang model and its implications. “In other words, the big bang should not be taken as evidence for a creator God since that God is hidden. Many like Lemaître who choose to believe in God despite the fact that his existence is far from obvious have little recourse but to assume that he must have reasons to hide from us. However, this “hiddenness argument” has been shown to fail.”
12. The discovery of the Cosmic Microwave Background (CMB) and the rise of particle physics. A look at the theoretical ideas behind the standard model.
13. An interesting look at the theoretical problems with the big-bang model: the flatness problem, the horizon problem, the structure problem, and the monopole problem.
14. Key concepts of science conveyed to the public. “Even when a model passes a test that could have falsified it, this does not mean that the model has been proved conclusively and will not someday be superseded by a better model.” Another one, “Major discoveries in physics usually lead to simpler theories with fewer adjustable parameters.”
15. Provides conclusions based on the best of our current knowledge. “In short, our universe had a beginning, but it need not have been the beginning of everything.”
16. Explains the concept of the multiverse. “The ‘World Ensemble’ or multiverse was motivated by established science—with no thought whatsoever to theology. It is the conclusion of our best current models of cosmology based on the extremely precise observations of modern astronomy and our best knowledge of fundamental physics.”
17. Eternal Inflation. “According to eternal inflation, once expansion starts it never ends, with new universes being created all the time. In 1986, Andrei Linde elaborated the idea, showing how it was possible that the universe reproduces itself indefinitely and “may have no beginning or end.”
18. The last chapter of the book covers some of the big philosophical questions. “However, based on our best current knowledge it is hard to imagine that in this immense universe there aren't countless planets with some form of life.” “Why should nonbeing, no matter how defined, be the default state of existence rather than being?”
19. Dr. Stenger takes glee in debunking some of the more popular arguments for theism including the Fine-Tuning Argument. “In short, nothing in our observations of the universe requires the existence of God. Furthermore, the absence of evidence that should be there for the actions of God rules out beyond a reasonable doubt the kind of God worshipped by most of humanity.”
20. Notes and formal bibliography included.
Negatives:
1. Though intended for the masses, most laypersons will struggle with this book. Elementary particle physics and astrophysics even at its most basic is challenging.
2. Surprisingly, this book is not as engaging as I’d hoped. It can be dry and even tedious.
3. A graphical timeline of the multiverse theory would have been helpful.
4. It requires an investment of your time.
In summary, this may be too challenging of a book for the layperson to really enjoy. Elementary particle physics and astrophysics even at its most basic will perplex the average reader plus the book does not do any favors by being too dry. The late Dr. Stenger does provide the public with a solid chronicle of the cosmos and makes a good case for the multiverse. A solid effort but may have limited appeal. Recommended for science lovers but not for laypeople.
