This discussion is about the encounter of a genius, Dr Carl Andrew Zapffe, with relativity physics. There are two main points. The first is that Dr Zapffe was not a fool or an ignorant person, he was trained scientist who, when he investigated the arcane details of relativity, discovered that Einstein had made a mistake. Being a conscientious person he felt obligated to bring this to the attention of the scientific community. Our story is about how his views were received. How one famous author of relativity books concluded that he was a “cod“, and how NASA rejected his idea to perform a crucial experiment that would determine once and for all the validity of the foundations of relativity.
