In his book The Science of Mechanics (1893), Ernst Mach Eric Weisstein's World of Biography put forth the idea that it did not make sense to speak of the acceleration of a mass relative to absolute space. Rather, one would do better to speak of acceleration relative to the distant stars. What this implies is that the inertia of a body here is influenced by matter far distant. This had a great influence on Einstein Eric Weisstein's World of Biography and in the development of his theory of general relativity.
