The four-dimensional collection of physical events in which temporal and spatial relations are represented together.
Special relativity uses flat spacetime; general relativity permits curved Lorentzian spacetime whose geometry is dynamical.

This is an authored directed relation from the source endpoint to the target endpoint.
A relativistic spacetime carries a Lorentzian metric encoding intervals, light cones, and causal structure.
A mathematical concept supplies part of the formal language, state space, representation, or analytic machinery used by a scientific or mathematical-physics concept. The source is the mathematical predecessor; this does not claim that physical content follows from mathematics alone.

Spacetime is modeled as the manifold of physical events; the edge expresses point-set composition, not a material assembly.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Relativistic spacetime is modeled as a smooth manifold so that fields, curves, and differential equations are defined locally.

General relativity treats spacetime geometry as a dynamical component coupled to matter and non-gravitational fields.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.

Minkowski spacetime is the flat, nongravitating special case of relativistic spacetime.
A more specific theory, model, entity class, or regime is obtained by restricting or extending the scope of a broader framework.
