Space-time in context

The meaning and nature of space-time are revealed by investigating the correct usage of relevant concepts rooted in reality. They are not unambiguous, as there are different concepts of space-time and their usage. In other words, space-time is given as a physical phenomenon within the linguistic game of the use of the concept of space-time and the corresponding physical theory. The theory plays the role of a rule (norm), and the practice of its applications is a "form of life" in the sense of the late Wittgenstein. There is a variety of space-time phenomena. Space-time is contextual, pluralistic and real. By changing our point of view, we move from one dimension of reality to another. The contextual realism of space-time is illustrated by examples from general relativity, quantum theory and string theory.
