  What I have so far presented and briefly formulated in the two  sentences of G, that alone impacts on physics and underlies the  actual individual investigations of problems of the theory of  relativity. Mach’s Principle, according to which the fixed stars  intervene with mysterious power in earthly events, goes far beyond  this [G] and is until now pure speculation; it merely has  cosmological significance and does not become important for natural  science until astronomical observations reach the totality of the  cosmos [Weltganze], and not merely one island of stars  [Sterneninsel]. We could leave the question unanswered if I did not  have to admit that it is tempting to construct, on the basis of the  theory of relativity, a picture of the totality of the cosmos.
