John D. Frey leads readers on a fascinating journey in this book that seeks to prove that Albert Einsteins theory of special relativity is all wrong. He begins by sharing an overview of special relativity, including its history, principles, and how these principles bring about time dilation and length contraction. The author examines six experiments that show that the theorys claims and principles can disqualify themselves by producing impossible, opposing results. He also explains how experiments that supposedly have verified special relativity and its claims actually help prove that the theory is flawed. Behind this book was over 10 years of research by the author concerning every aspect of special relativity. In addition, the author consulted with over 30 professors of physics concerning his ideas and experiments and their feedback was extremely important in the creation of this book. Written in everyday, nontechnical language, the book will make sense to those without a background in physics. No matter what you do for a living, you can participate in a vital discussion about our universe and join the author in Challenging the Unchallengeable.
