  During 1934 Milne worked together with his new student A.G. Walker. Walker never evinced much interest in the philosophical aspects of kinematic relativity, choosing instead to focus tightly upon working out the physical details of the theory itself. He had immediate success (Walker 1934). One of his important conclusions was that other authors, specifically McVittie and Robertson, were wrong to conclude that the physics of Milne’s theory ultimately corresponded to relativistic cosmology: “Milne’s system is fundamentally different from that of general relativity.” (Walker 1934 p. 489; emphasis in original)
