I think this quote from Terry's website explains a lot about his theory, although not why he thought hit and run advertising for his book would work here:
At long last, a theory has emerged that addresses the foundation of reality logically, rationally, empirically, and completely - Null Physics. The universe it reveals doesn't rely on unknowable precursors in the ancient, untestable past. The universe it reveals won't collapse, or grow old and die. Null Physics tells us why the universe exists, how the universe exists, and why it is the way it is. The mystery of our existence has beaten scientists and philosophers for so long that they are utterly convinced that reality's underpinnings are beyond human comprehension. They are wrong. Anyone with a basic familiarity with high-school physics can, by reading this volume, understand the universe with a greater depth and clarity than is currently believed possible. Welcome to 21st century physics.
