TheAlexKnapp writes: The Nazis winning World War II by getting the bomb first is a staple of alt-history and it's the reason why James T. Kirk lost the love of his life, Edith Keeler. Einstein also noted possible German efforts to build one in his letter to FDR urging the U.S. develop an atomic weapon. But it turns out there really wasn't a race to build a bomb at all. Materials from Germany's atomic weapons program have been studied by an international team of researchers, who determined that Germany never achieved a self-sustaining nuclear chain reaction — something that Fermi and his colleagues had accomplished in 1942 — which was a key step to actually building an atomic weapon. This chemical evidence supports other historical accounts that the German atomic program never achieved this result.
