As I’ve shown, there are three dimensions of time as well as space. That makes six dimensions in all, which I’ve written about before, such as here. There may be reasons to use the full potential six dimensions but usually it is better to contract that to four or two dimensions. We need terms to distinguish each possibility.
In classical physics and everyday life space and time are considered separate. It is common to contract 3D time into 1D time by considering only the total duration of motion. This may be expanded back to 3D time as needed.
Here are terms that refer to space and time as modeled by relativity theory:
Potential space-time (or time-space) is a six-dimensional continuum with 3D space and 3D time that models relativity theory.
Space-time is a four-dimensional continuum with space in 3D and time contracted to 1D that models relativity theory. The version associated with special relativity is called Minkowski space.
Time-space is a four-dimensional continuum with space contracted to 1D (the stance line) and time in 3D that models relativity theory. 1D space contains only the distance from a reference event.
Contracted space-time (or time-space) is a two-dimensional continuum with space and time contracted to 1D each that models relativity theory.
In classical physics and everyday use in which space and time are considered separate, the corresponding terms are as follows:
Potential space and time (or time and space) indicates 3D space and 3D time as separate continua.
Space with time indicates 3D space and 1D time displacement as separate continua.
Time with space indicates 1D displacement space and 3D time as separate continua.
Contracted space and time (or time and space) indicates space and time contracted to 1D each as separate continua.
