As first analyzed by Hermann Bondi in 1957, matter with negative mass is consistent with

the structure of Einstein's general theory of Relativity. Although initially the concept was

considered just a theoretical curiosity, negative mass, or "exotic matter," is now incorporated

into the body of mainstream physics in a number of forms. Negative mass has a number of

rather non-intuitive properties, which, as first noted by Bondi, and then later commented on

by Forward (1990), Landis (1991), and others, results in possible applications for propulsion

requiring little, or possibly no, expenditure of fuel.

"Young Men: The Magazine for Tomorrow's Technicians and Engineers" was published by the John Raymond Company during the 1950s. John Raymond was a publisher known for his involvement in men's magazines but also ventured into science fiction and technical publications during this time. However, specific details about the ownership beyond the initial launch in the 1950s are not as clearly documented in the provided sources or general web information.
