| Space-time, philosophy: space time is a three-dimensional space with time as a fourth dimension. The fact that time is interpreted as a dimension distinguishes the space-time from multi-dimensional mathematical spaces, in which time plays no role and which are therefore structured differently. In particular, the space-time has no measure which can equally be used for spatial distances as well as for time measurements. See also relativity theory, four-dimensionalism, world lines._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Albert Einstein on Space Time - Dictionary of Arguments
Kanitscheider I 164 Event/General Theory of Relativity/Kanitscheider: every event is a point in four-dimensional space-time that can be described independently of all conceptual constructions such as vector bases and coordinate systems. Space-time/Einstein: somewhere between 10-15 and 10-33 cm the smooth manifold image of space-time breaks down. >Gravitation/Einstein, >Covariance/Einstein. Space-time/Kanitscheider: A space-time also has more general qualities than the metric, namely affine, projective, topological. Kanitscheider I 166/167 Def light cone/Kanitscheider: shows the character of Einstein's gravitational theory well: if we pick out a point e in space-time, it represents a physical event. The cone of light from e is then the story of a spherical flash of light that converges inward towards e and then diverges outward again from e. The cone of light reflects the local causal structure of the Relativity Theory. All allowed processes are represented by world lines lying inside or at most (in the case of photons and neutrinos) on the mantle of the cone. All events in the past cone can affect e and all in the future cone can be affected by e. The gravitation-free space-time of the SR (matter-free universe) can be distinguished from the generally relativistic space-times filled with gravitational fields by the local light cone structure. In the SR (without matter) the cones are all arranged the same. In the AR (with matter) they are inclined according to the strength of acting gravitational fields. (Effect on the causal structure and time by the gravitation of matter). Kanitscheider I 170 Space-time/Einstein: over time, Mach's principle lost its weight and space-time was prioritized by matter! She took on the properties of material objects. >Mach's principle, >Theory of relativity, >Space-time/Kanitscheider._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
