Bernulf Kanitscheider on Weyl Principle - Dictionary of Arguments
I 161 Def Weyl Principle: The galaxies lie on a bundle of geodesics that have no point in common except for a single point in the past from which they diverge. The fact that the galaxies rest in the instantaneous flat triple space is expressed by the fact that the world lines intersect it orthogonally. The Weyl principle represents a forerunner of the co-mobile coordinates used for the homogeneous and isotropic FWR worlds. Def geodesic: The line in space on which freely falling bodies move without the influence of forces, timelike. >Time-like. Def zero line: orthogonal to the geodesics: line on which the light moves, no time. As a result, space-like. >Space-like. Def world lines: geodesics and zero lines. >World lines._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
