On December 27, 1949, The New York Times ran a story titled "New Einstein theory gives a master key to the universe" in reaction to the new appendix in the book's fifth edition in which Einstein expounded upon his latest unification efforts. Einstein had nothing to do with the article and subsequently refused to speak with any reporters on the matter; he reportedly used the message "[c]ome back and see me in twenty years" to brush off their inquiries.
