Book Review: Who's Afraid of the Multiverse?

Introduction

As a Christian who is deeply interested in the sciences and what they bring to the table for defending the existence of God (and the truth of the Christian worldview, specifically), I have often encountered the idea that multiple worlds may exist, which seems to explain away the beginning of the universe and its designed features. When I heard that astrophysicist Jeff Zweerink (Apologetics 315 Interview) wrote an introduction booklet addressing that very challenge, it caught my attention. "Who's Afraid of the Multiverse?" (paperback, Kindle, Video) provides an introduction to the concept of the multiverse and what its implication is for arguments for God's existence. It is a short read at only 53 pages.

The Multiverse Landscape

Zweerink spends the first half of the book setting the stage for why discussions of a "multiverse" are even necessary and explaining what scientists mean by the term. Various observations of the universe have led scientists to believe that the universe experienced a period of expansion speeds exceeding the speed of light. Though the evidence is strong that this took place, exactly how and what caused it to begin and end are currently under investigation. One of the types of multiverse is a necessary implication of the fact of inflation, and one of the other types is a necessary implication of a particular model for the possible mechanism of inflation. Each progressive type becomes more speculative and enjoys less scientific evidence than the previous one.

Lawrence Krauss, Astrobiology, and God

Introduction

The other day Eric Metaxas wrote an article for the Wall Street Journal entitled "Science Increasingly Makes The Case For God." Anti-theist astrophysicist Dr. Lawrence Krauss took notice and wrote a response "No, Astrobiology Has Not Made The Case For God" that attempts to undermine Metaxas' conclusions. Today I will address several of Dr. Krauss' arguments in his piece from scientific, philosophical, and theological perspectives.

Krauss takes issue with the teleological argument- the fine-tuning of environmental conditions and the fundamental constants of the universe for the origin of life. His issue is with the probabilities. He summarizes the argument as multiplying independent probabilities of every necessary event to reach a probability so low that it is indistinguishable from zero, thus chance is eliminated (from the three options of chance, necessity, or design to explain life's existence). Krauss argues that the probabilities of each event that leads to life's origin that are calculated are not independent of one another. His concern is that each event is calculated independent of all necessarily preceding events. Meaning that any event in the chain leading to the origin of life will increase the probability that the next necessary event will take place. Thus the probability is not as small as one may think.

Book Review: Origins of Life: Biblical and Evolutionary Models Face Off

Introduction

How did life begin? This question has perplexed humanity for centuries. Some people believe that it came along by natural processes. Others believe that a divine Designer is behind it all. These two options go head-to-head, tested against the latest scientific research in the book "Origins of Life: Biblical and Evolutionary Models Face Off" (hardcover, Kindle, Supplemental Site) by astrophysicist Dr. Hugh Ross and biochemist Dr. Fazale Rana. The book is divided into three sections, seventeen chapters, and 298 pages (including notes and appendices). This review provides a chapter-by-chapter summary of the contents of the book, but it must not be accepted as a replacement for reading the book, itself. The review will conclude with my thoughts and recommendation.

Drs. Ross and Rana take the position that the origin of life is by divine design. To scientifically test their hypothesis, they present their model, competing models, and the latest research; they then compare the predictions of the models to the research to build their case. Before examining the current state of origins research, it is a good idea to take a quick look at the events that led to the current state.
