It's all about The Big Bang, and how Scientists until the latter parts of the 1920s, long having accepted the idea that the universe was eternal and static, were almost universally repulsed by the theory of the Big Bang and the idea that the universe actually had a beginning. Course, famously, even Einstein originally was in denial of this, as he had argued for his "Steady State" ideas - going so far as to fiddle with his equations (related to General Relativity) to buttress it. Eventually, as most know, Einstein considered this folly his "greatest blunder." Before finally accepting the Big Bang calculations and redshift star evidences, many were disturbed by the philosophical implications of a universe with a beginning - as in, "If there's a beginning to the universe, then there must also be a BEGINNER!"
Dr. Meyer's book is heavily footnoted with 71 pages of notes and a 32-page bibliography. It offers powerful evidences of a designed universe, aimed at critics, with lengthy, detailed explanations.
Here's a short interview Dr. Meyer did with Dr. John Ankerberg about the Big Bang and the history leading up to it theoretical development:
