|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.

Space time points/space time/Field: have complete causal action capability. Then one can even do without electrons. - Instead: mass, charge, etc. of the electron as properties of the space time regions.
Space time should be given priority to the field, if there are several fields.
Spacetime points/Field: are not abstract but empirical.

Space-Time/Field: differs from space not only in that it is 4-dimensional, but also in the fact that it has no full Euclidean structure. - And it also has an extra structure that is not present in the 4-dimensional Euclidean space. - Spatial distance cannot be objectively compared with time, although one could arbitrarily define a comparison. - (e.g. with uniform movement).
((s) Space time/space-time/(s): Non-Euclidean, since no common measure for lengths and durations - different: R4 (four-dimensional space) - here there is a common measure in all dimensions._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
